These videos have helped me to help my son, who sits his GCSE exams starting tomorrow. Thanks so much for such a great way of teaching all of these subjects. There really is no reason for parents to shy away from helping their kids with such great help and the manner in which you teach these really does aid learning.
Love it! I'm in school right now and they just dropped a sneaky little trig class out of nowhere, I'm sweating bullets, this is a great video, I wouldn't mind seeing more of these just for repetition, all the other videos from others just confuse me, well done to you sir
idk if this helps anyone but here's some quick definitions of stuff: theta - angle opposite - the opposite end of the angle adjacent - beside the angle hypotenuse - what makes the triange a triangle (longest side) some better stuff to lower confusion: arcsin/sin -1 ---they both mean the same thing just laid out differently (same goes with cos and tan)
I got excited at the "friendly equation" to the side, I had no idea other people did that! got me through loads of chemistry, glad you're spreading the word about it:)
After completing this video I agree that trigonometry is one of the most feared topics in mathematics. I learned that trigonometry only works on right angled triangles. I learned that the length of the sides are named (a, b, c) due to its respectively opposite angle. I memorized the 3 equations as SOHCAHTOA. Allow me to demonstrate it: Sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse and tangent equals opposite over adjacent. Sine= SIN, Cosine = Cos and Tangent = Tan.. As I was watching this video the lesson became easier and easier. You are already provided with 1 angle which is 90 degrees and more information will be given to complete it. All you have to do is place the numbers in the right place according to the equations and simplify them to get your results. Your final answers may turn out in decimal numbers. Don't freak out, just continue and don't overthink it. If your teacher allows the use of calculators, you will be able to do it on it. However, only use the calculator to make sure of your answers or if huge numbers are given. I honestly thought I would have numerous questions to ask. However, I watched various videos before this one. The way you explained it was phenomenal. Great Job!!!!!
memorizing SOHCAHTOA isnt a really good way of understanding the sin, cos and tan functions. I'll give you a better more geometric interpretation of these functions. So, if you take any point A, on the unit circle, (circle with a radius of a unit, in the cartesian plane)draw a line to that point and the origin, (0,0), and draw a perpendicular to the X axis, and then join that point on the axis back to the origin, you get a right angled triangle. The line you just drew to the X axis is the sine function! Isn't that cool? The math is pretty simple, since sin = opp/hypt, the hypt will always be 1 as its the radius of the original circle so it will always be just the opposite side. Similarly, the compliment function to the sine, aka cosine or cos is the line you drew from the point on the x axis and the origin. Same math. The tangent function is the point you get by drawing a *tangent* to that unit circle at that point A (yes, thats where the tan function gets its name). The segment you get by taking the distance to that tangent segment and the X axis gives you the tan function, and the segment you get by joining the tangent to the Y axis gives you the compliment of that tan function, aka cotangent or the cot function. So just by using pythagoras' theorem you can derive the ratios on the spot, without ever needing to memorize it
Also, if youre interested in calculating any value of sin(x) without knowing the opposite or the hypotenuse, there is a very beautiful series, called the taylor series. According to this series, the value of sin(x) = (x^1/1!) - (x^3/3!) + (x^5/5!) - (x^7/7!) + (x^9/9!) and so on forever. Truncate at any point, and you get a veryy good approximation of sin(x). This is also btw what calculators use to compute the value. similarly, cos(x) is the same as sin of x, except it has every other even number, instead of the odd number pattern of sin(x) If you dont believe ill solve an example out by computing the sine of 1 as i said sin(x) = (x^1/1!) - (x^3/3!) + (x^5/5!) - (x^7/7!) + (x^9/9!) so therefore sin(1) = (1^1/1!) - (1^3/3!) + (1^5/5!) - (1^7/7!) + (1^9/9!) (and i chose one cause powers of 1 are easy to compute) sin(1) = 1/1 - 1/6 + 1/120 - 1/5040 + 1/326880 sin(1) = 1 - 0.16667 + 0.00833 - 0.00019 + 0.000003 = 0.83333 + 0.008311 + 0.000003 = 0.841664 which is a very good approximation of sin(1). (actual value being ~0.8414)

Thank you very much. I'm a 25 year old guy and I needed to know how to find an angle's number for a personal project. I've studied these things when I was in high school but never understood them until today.
Thank you so much for this. I struggle to learn math at school because of my autism and trigonometry has had me in a choke-hold all this time. But this video helped me so much; I'm getting the hang of it. I may not know it fully but this has done wonders keep up the good work.
In my 37 years...i never knew how beautiful this was. I never gave trigonometry a chance. it sounded scary to me. but...this is beautiful! i like how you can see the math and the relations. this is literally eye opening. now i understand how a person can tell how tall a building is just with an angle. also....this means that rectangles are really two right triangles kissing hypothenuse. so you can do some fun stuff with other shapes as well. then if you need to measure that rectangle...you can split it into one triangle...and just measure that and BAM since the other triangle is a mirror reflection...whatever you do to one you did to the other. lets say you need to find the center point of side A. the opposite triangle has a side identical to A as well. so you can make a cut on A and then a cut on the other A and its the same. you dont have to measure again (if it is a perfect rectangle). that means...if you need to break a rectangles parameter into 8 equal parts...you can break it into two triangles first....then focus on breaking one triangle into 4 equal distant parts.....and you basically found the 4 on the mirror reflection of that. you found 8 equal distances of a rectangle without having to measure the entire thing out. i need more math! honestly never noticed how important and beautiful and mysterious it can be.
i like the way you explain it, you say pointless things to fill up a little bit of time so its an easier pace to absorb the information, very good thumbs up 👍
I know im a month late, but just look up trig practice worksheets and theres literally endless amounts, be specific with what u search tho so u get precisely what you want.
for 6:00 . For 0.57 = x/12 i would say that 12 is multiplied by 0.57 because its going to the other side of the equal so it will be inverse as 12 was originally dividing with x but when it is put to the other side of the = sign it becomes multiply. Likewise for the other symbols + become - etc 👍
Thanks . I always remembered soh can toa but never knew how to apply it to a right side triangle. I guess I missed that class when my teacher showed it. Anyway I am now 48 years old and came across your video How simple. I can't beleive not one teacher couldn't see i was struggling with this and could not explain it like you just did. Thank you
I like this video but it seems trigonometry is ultimately 'How to use your calculator.' Any chance of a run through without a calculator including all basics needed to work it out the old fashioned way? Cheers.

@robo0o what did they say if u remember
Thank you very much. I'm a 25 year old guy and I needed to know how to find an angle's number for a personal project.
I've studied these things when I was in high school but never understood them until today.
Wow thank you! Your explanation was great. I feel like I actually understand how all the concepts work together now.
This guy is actually making sense unlike those cringe-ass music videos.
Way to break it down into a very understandable video. Thank you!
5 years later and VERY EASY! Thanks man. Needed this for my university diploma studies as a refresher.
He made a mistake. The cos -1 (.71) = 44.77 degrees not 45.1 degrees
Thank you so much for this. I struggle to learn math at school because of my autism and trigonometry has had me in a choke-hold all this time. But this video helped me so much; I'm getting the hang of it. I may not know it fully but this has done wonders keep up the good work.
Thank you so much, this was better than my 1hour class!
In my 37 years...i never knew how beautiful this was. I never gave trigonometry a chance. it sounded scary to me. but...this is beautiful! i like how you can see the math and the relations. this is literally eye opening. now i understand how a person can tell how tall a building is just with an angle.
also....this means that rectangles are really two right triangles kissing hypothenuse. so you can do some fun stuff with other shapes as well.
then if you need to measure that rectangle...you can split it into one triangle...and just measure that and BAM since the other triangle is a mirror reflection...whatever you do to one you did to the other. lets say you need to find the center point of side A. the opposite triangle has a side identical to A as well. so you can make a cut on A and then a cut on the other A and its the same. you dont have to measure again (if it is a perfect rectangle).
that means...if you need to break a rectangles parameter into 8 equal parts...you can break it into two triangles first....then focus on breaking one triangle into 4 equal distant parts.....and you basically found the 4 on the mirror reflection of that. you found 8 equal distances of a rectangle without having to measure the entire thing out. i need more math! honestly never noticed how important and beautiful and mysterious it can be.
Hello sir. Thank you. I was struggling with trigonometry,and now I can remember all of it.
Thank you for your time! I'm 5 years out of high school and starting college this year so these kinds of resources are invaluable to me.
Silly old harry Caught a haddock Trawling off Australia. That’s what we were told
I was told silly old Hitler couldn't advance his troops over Africa 😂
@@tom-ez1np This Hitler one is easier to remember, but I don't like giving props for Hitler.
I am only thirteen and you have fully explained trigonometric functions to the point I find them easy, you are extremely good at this.
Hello! I really enjoy watching your videos! I understand them so much thanks!!
The 3 equals 6/2 was the most clutch thing I’ve ever seen in my life.
can you kindly explain how you got 0.57.
If you enter sin(35) into a calculator, you will get 0.57 as a result
i like the way you explain it, you say pointless things to fill up a little bit of time so its an easier pace to absorb the information, very good thumbs up 👍
Hey Mate,
Thanks for the wonderful explanation, just wondering if you could have any practice worksheets related to this?
Thanks
I know im a month late, but just look up trig practice worksheets and theres literally endless amounts, be specific with what u search tho so u get precisely what you want.
@@glography where did u find them?
@@GlizzyGobler9000 try khan academy
Thank you. I didn't want to cry during trig for the first time. Absolute legend.
i hope you get 100 lottery tickets and win all of them
I have been through countless videos and none of them explained it better than this one thank you so much you have saved my life
I'm doing mechanical engineering just started never thought it would be so heavy with maths
Engineering seems like something that would require quite a lot of math
Is it not more physics based than maths
@@Anonymous_56789 it's both and they put them in long confusing questions
Love the friendly equation idea..lots of my students stumble on this step.
This video is simply INCREDIBLE, thank you!!
love this vid was really struggling because i couldnt understand the way my teacher was teaching me and this really helped.
0:01 meth channel 🤨
3:13 💀
for 6:00 . For 0.57 = x/12 i would say that 12 is multiplied by 0.57 because its going to the other side of the equal so it will be inverse as 12 was originally dividing with x but when it is put to the other side of the = sign it becomes multiply. Likewise for the other symbols + become - etc 👍
For the second one he did would it be 15 times by 1.11 since you change the signs? I’m a bit confused on this bit
If a person did not use a calculator, what is the formula from cos to get the degree of the angle?
If x is your cosine value, the angle is approximatly (180*(π/2 - x - x³/6 - 3x⁵/40 - 15x⁷/336))/π degrees
@@HakanTheUltimateHoca In other words, good luck not using your calculator
You saved me for my end of year exam. Thank you so much!
SO HELPFUL!!
Thank you so much! I have been struggling with this for days and I finaly understand it!
Thanks . I always remembered soh can toa but never knew how to apply it to a right side triangle. I guess I missed that class when my teacher showed it. Anyway I am now 48 years old and came across your video
How simple. I can't beleive not one teacher couldn't see i was struggling with this and could not explain it like you just did.
Thank you
Soh cah* toa. Although I'm going to assume that's autocorrect's doing
@@TLPH04 lol yes the beautiful auto correct. Thanks
Thank you so much for this tutorial, I'm currently less than 8 hours away from a maths test, and this just saved my life!
Thanks for the help
great way to remember 2:57 is oh hell another hour of algebra
That’s amazing!!!!
I like this video but it seems trigonometry is ultimately 'How to use your calculator.' Any chance of a run through without a calculator including all basics needed to work it out the old fashioned way? Cheers.
same thought! it would be great without the use of a calculator, to get a better understanding.
You are awesome. I’m completely taxing my children your methods. Makes it way more simple to understand and get correct answers!
W to all those who dident listen in class and decided to just search it up
Pov im in grade 11th and have 20/100 grade in math 10c
I've just just started trigonometry in maths and after 1 hour of my teacher trying to explain it to me and not understanding it , your method made me understand it all , thank you so much
Thank you for the video sir
This really saved me
I have a trigonometry test in 2 days and it's really gonna help me
How did it go?
@@sahilpatel0701 I can't even remember but I'm pretty sure I passed that test
@@dhruvkore1324 ok nice 👍
When trying to become a pilot trigonometry is #1. This video definitely helped me get a better grasp
