me already sweating at the first question 💀
I in 6th grade and i sweating real hard on the 3rd question
Here’s a quick answer: No
Da stoo bid. You fail da math den you fail da rife.
Here’s a long answer: Noooooooooooooooooo
@@Grassmpl Not true, no one uses this type of math in the real world
@@SayWhat336 ehhh not really its usful for calculating trajecturies of thown objects in coding
Good video! I got 11/12 of the questions, but was stumped on the last one. Keep making videos!
Same for me.
The last question is a topic gone over in vector calculus in which you have to minimize the distance formula. I learned this freshman year of college. This isn’t a grade 12 level question 😂
It is in Ontario
Nice video! Loved trying to solve things, very interactive and also refreshing seeing things from other perspectives. I hope to see more from you!
I’m a math tutor and I have only seen the first question, and it wasn’t a problem. However, to suggest that it was an “easy” freshman year problem is a bit misleading.
Is it really all too difficult for a 9th grader? I'm not familiar with the term freshman but I learned that at school on the 8th grade and some advanced schools (from friends that I know) they got hit that by the end of 7th grade.
@@slaire6892it’s typically an algebra 2 question
Very exciting. Great test for me. A lot I didn't know. Never used Pascal's Triangle, so that's something new. Dot products I didn't use till college engineering. So lots to review and new territory to explore.
POV: binomial theorem from the hardest level of maths in Scottish schools (equal to degree year 1) has been called ‘easy high school maths’
This is 'easy high school maths' in scotland too. Probably 3 marks at the start of the paper and thats generous.
POV: first question is from 8th grade
Great video to procrastinate to at midnight instead of writing the final physics essay. Also great explanations to the actual questions. Still at Grade 10 maths at the moment but I was still able to answer and understand the questions at a higher level
Bro I’m literally in the exact same situation, have a physics lab report due tommorow midnight and want to ask my teacher questions it before school tommorow it’s only half done rn lol😂
As a Grade 10 from Asia, I expect it to be so hard, but almost got correct (except gr12 medium, hard) .. Every questions is just algebra so it's easy. I've already take Pre-Calculus course and still ongoing. Gonna take Prob&Stats soon...
take calc not prob or stat
Pretty nice, 10/12. I couldn't answer hard for grade 9 and grade 12 easy. Forgot some basic stuff. Nothing to difficult, nothing too crazy just quick and easy problems with "telegraphed" answers that scratch the mind.
Nice video, a few 11th and 12th grade are taught in 9th grade in my school.. but there were definitely a few tricky ones
I was able to solve up until grade 12 (hard) and immediately could not recognise the question in this part. Thank you so much for helping me through it! ❤ I had found this question to be the hardest and the rest to be easier (relatively) to solve
10:43 Draw a parallel line to the bottom line with the length 10 from the 40° corner to the right side. Then u have an 90° angle and you can use right triangle trigonometry
Oh man thats what I also did,btw Im in grade 9th in India
@@neerajrai5464you think that’s a flex 😂 try doing complex analysis senior year of high school
@neerajrai5464
Don't post your grade and nationality on the Internet. It's a dangerous place
@@thesoulknight8377 neither of those are sensitive information and are so broad it won't narrow anyone down, and what's someone gonna do with that information anyway? it's no big deal to give grade level or country online in a random comment section, cause there's millions of people in school in india or any country
of course name, precise location, or anything like that is better not shared, but "9th grade in india" is not nearly the same as those, nothing dangerous could come from information as non-specific as that
@@Hypnotic.-.Not a flex lil bro
10:48 I used less work by splitting it into 2 right triangles and using tangents, but I also solved it using sine law to check my work.
For the grade ten medium question, you could do it another way. I multiplied the 2 in front of x^2 with the 48 to get x^2-22x+96=0. I used the factors -6 and -16 for 96, which add up to make -22. Then I factored and got (x-6)(x-16). Then I divided both of the constants by 2 to get rid of the multiplication in the first step. Then I arrived at (x-3)(x-8)=0, from here I got x=3, and x=8.
Or use delta and if it's positive you will get x1 and x2
Grade 10 Aus here, was able to do all except grade 12 hard. Haven't done topics regarding the last one yet though.
Fun video :)
I'm currently in 9th grade, and I solved the 9th grade question with ease. It was quite simple
In Germany we know all of the first questions by 8th grade...
Now I get why you need college in between highschool and university.
3:45 (if 5/2 used we get mirror image, not 90deg angle, has to be -5/2) 10:05 10:45 11:30 14:04 21:45 (complicated, intervals are simpler) 23:00 (at MIN and MAX point derivative = 0) 28:45
Easiest 12/12 for me. These are mostly meant for the grades you mentioned. I saw them one year earlier
Absolutely
I'm going to disagree about the grade 12 hard problem being high school math. I didn't even get introduced to math in 3 dimensional space until 3rd semester Calc in college.
in my high school we are doing that right now, it is called calc 3
@bene2451 Cal3 is not high school math. You can learn college math at the middle school level.
i am currently taking mcv4u (calc. and vectors) and yes, planes are the last unit we cover
We did that in 2nd to last year of high school (UK). It’s one of the first chapters in A level FM, which many students who go into STEM at uni do.
depends on what math track you're on. taking calc bc in your junior year of high school and multi senior year is actually quite common
Forgot a lot of this stuff, especially trigonometry 😢
11/12, I couldn't go the last question because I'm not a fan of vectors, but nevertheless, interesting!
What topic is the last question testing? It’s the only point I haven’t reached in maths and it sounds interesting. I’ve taken vectors, but not in 3 dimensions.
3d geometry
Its just vectors in 3d
Got about to grade 10 medium mentally and I don’t got anywhere to work out so I couldn’t go on also it stopped making any form of sense after grade 10 hard
Almost all of them
I just graduated 11th grade and I have no idea what Pascal's triangle is...
Crushed all of em except grade 10 3rd problem as it had calculations
In year 9 rn, 10/12
8:26
Length of hypotenuse from Pythagorean theorem
c^2 = 2^2+10^2
c^2 = 104
From sine law
y/sin(90-alpha) = x/sin(40)
y/cos(alpha) = x/sin(40)
y = cos(alpha)/sin(40)*x
cos(alpha) = 10/sqrt(104) =10/(2*sqrt(26))
cos(alpha) = 5/sqrt(26)
so y = 5/(sqrt(26)*sin(40))x
From cosine law
x^2=104+25/26*1/sin^2(40)*x^2-2*2*sqrt(26)*5/(sqrt(26)*sin(40))x*cos(40)
x^2 =104+25/26*(cos^2(40)+sin(40)^2)/sin^2(40)*x^2 - 20*cot(40)*x
x^2 = 104+25/26*cot^2(40)*x^2+25/26x^2- 20*cot(40)*x
1/26*(25cot^2(40)-1)x^2- 20*cot(40)*x + 104=0
(25cot^2(40)-1)x^2 - 520*cot(40)*x + 2704 = 0
This gives me quadratic equation but I cannot eliminate one of the solutions of this quadratic
Exactly how i did it!
2x²-22x+48=0
x²-11x+24=0
(x-8)(x-3)=0
x-8=0
x=8 ❤
x-3=0
x=3 ❤
loved this video, here are two notes i have
much easier solution to the grade 9 hard question is:
y+3 = (2/5)(x+2)
surprised you didn't do that.
on the grade 11 hard question, x can definitely equal -11. Since (x+11) cancels out, it's no longer a part of the expression, and x can equal -11. I also checked this on desmos, and x=-11 was very much a point on the function.
x=-11 means the equation will be 0/0. I believe it makes sense in case of limits but the actual value of x cannot be -11 as it makes the equation undefined.
It’s undefined at x=-11 since it evaluates to 0/0
x = -11 is not a solution. There is a "hole" in the graph at that point. If you look on Desmos, there is no intersection of the graph in the original problem and the graph of x = -11. Also, if you plug -11 in for x in the original expression, you get 0 in the denominator.
x=-11 only works for the simplified expression. If x=-11 during any of the other steps, it would be undefined. When we cancel out the x+11 terms, if we have x=-11, we're dividing 0 by 0. For the final expression, sure, x can be -11. However for the question at hand, x cannot be -11. It's limit does exist which is also why the function seems continous on desmos, but if you put your cursor on the point x=-11, it shows that y is undefined (as long as you put in any of the steps before cancelling the x+11 terms)
I hope that was easy to understand :) I'm not the best at explaining stuff lol
The restriction of x = -11 is necessary in order to state the simplified version is equivalent to the original expression. Inputting x = -11 in to the original give 0/0 but in to the simplified version gives -11/40. If we don't state the restriction, we can't state equivalency. Hope that helps!
For everyone here, on the grade 9 hard problem, you can also use point-slope form and get the answer.
Failed on grade 11 easy. I’ve had experience with Pascal’s triangle but not any stuff with exponents inside of the parentheses.
failed every questions lol
the worst thing is that I have like 85/100 in maths (im 18 yo)
I am in grade 12 and we did all of this already and do integration by parts or substitution and that’s difficult
if you are still doing IBP and U-sub then I don't think you've done the third grade 12 problem
Our teacher chooses to do Vektors before e funktions because e funktions are part in stochastic
That vector problem doesn’t seem high school level. I also wonder if that double triangle problem is doable without a calculator.
I still dont understand how can people find the non-common values of inverse trignometric functions without a calculator
@@lakshya4876there’s a trick you can learn with your hands, we learn it when we’re 11/12 in Europe
@lakshya4876 they can't. You have to use a calculator I'm pretty sure.
the only one slightly challanging was the triangle one
5(y-3)-3(y-4)=12
5y-15-3y+12=12
2y-3=12
2y=15
y=7½ ❤
That first question would be i think hard for a freshman, no?
got 11/12, the 12th question was hard since im still in 11th grade and we still haven't learned physics yet so i was not yet able to solve it yet. anyways nice video to pass time off
Question 12 isn’t a physics question 🤔, It uses concepts that you learn in the earlier stages of college from what I can tell, we learn it before college in Europe [about 16/17 were introduced to the concept]

32x^10 -248x^8 + 720x^6 - 1080x^4 + 810x^2 - 243
mid way through the video, and i wasn't able to do qs 6 because I didn't know you were allowed to use calculators, inn my country you are't allowed to use calculators to solve questions so we would not get question like this
In germany grade 12 involves: derivatives (chain rule, product rule,…), integration, vectors, highschool math just seems way easier
yea, same with every other country... all of that stuff is usually high school math unless you choose to delay a year. In some American schools we take derivative and integral calculus in 11th, and calc 3 or linear algebra in 12th
Im at year 7 and I find like half of these problems doable lmao
Got the first one right....quit while i am ahead.....
👌🏻✨
Bro grade 9 level maths in this vid are asked in grade 6-7 in
India thats also in eazzy section. And we are taugth simultaneous in class 8 only.
And quadratic equation in class 8 only
I will be starting grade 11 in about a week but I still solved till medium level question of grade 11
I also did hard question of grade 11
Im 9th grade now and I got to grade 11 easy and i can't past grade 11 medium is that good
11:23 if you learn Calculus 1, you will realize that you could do the derivative repeatedly until the power of the exponent gets reduced down to one, via the use of power rule and chain rule
But that isn't the same as the function. Derivative is the rate of change
Look at the timestamp again
that would be a whole different function then
My dumbass completely forgetting Pascal’s triangle but blowing through the 12th grade questions😅
Light work no reaction🗿🍷
:/ why cac as Bangli i confused what is csc and google this cosecant why Short form
Grade 11 hard seems way easier than the medium question
I use to be a pro in AP Calc in high school 😢
Here is when I noticed my country's education ;-; yeah i'd written this with my feet
As someone who is at high school i belief i can pass it
Belief is crazy 💀
Ok im a 7th grader and heres how i did:
1.correct
2.correct
3.correct
4.correct
5.correct
6.correct
7.didnt really remember how to use pascals triangle so wrong
8.correct
9.i got the restrictions correct but i didnt realize it could be simplified further than adding them
10.i dont know much about solving inequalities so wrong
11.correct
12.no idea about 3d graphing so wrong
overall 75% or 80% not bad.
Another math genious. Hi! >w<
I am an 8th grader and I got everyone correct too. How did you learn about this? :3c
its a 66%, and I know for a fact that you didn't get number 11 in seventh grade, you don't even know what a derivative is
Is calculator allowed ?
Yes but only for the 3rd question of grade 10th as it uses trigonometry
No!! Use your brain 🧠
@tastyfood2020 Yeah sure let me just calculate inverse trigonometric functions of non exact-values using my brain
cant even send or write on the board is 12?
First q is 9th grade eq? Pfffff, we learn in 7th grade
I could understand up to 10th grade easy but I'm in eighth grade
I am in 7 grade I got all correct except last one
whats 7C3
you didn't get the second to last question, its calculus and you're in 7th grade...
@@bene2451I believe you can use comp math techniques to find local extremes, root bashing and Vietas algorithm come to mind
I am in grade 9 and I got all of it correct except the last one.
Same but i am grade 7
They’re all simple, last one is a little trickier but one of the easiest 3 dimensional questions you’ll come across
I learned most of the math myself so I don't know how people in school would solve it, but for the last one, I think I made it a little too complicated. ^w^''
I used an sphere equation at (4, -4, 1), then solved for the radius which gave me another equation, and I then searched for the smallest value this equation can be using only real numbers...
that's not how you would solve it at all...
20:39 The last term of lhs is 14 not 4
When you subtract 10 from both sides, 14-10 = 4, so the expression has a 0 on one side and a 4 on the other. This makes it easier to solve :)
No it is 4, because after transposing 10 to the lhs, that becomes 14-10=4
My dog passed it.

I hate watching other people take too long to do easy problems.
It's not easy for everyone.
