You have literally saved me from failing an exam. I am joining your member channel tonight, after work. I have upcoming Calculus, Chemistry, Physics, Org. Chem.classes in the future and I will need your expertise!!!!!!!!!!!!! Thank you for making math less intimidating. You are a gift!!!
this was explained perfectly, I was so stressed bc during lectures I did not understand what was going on. you went over basics and it helped so much!!
I am Iraqi. I loved your method of teaching. It is wonderful. Thank you. You solved me a lot of problems in mathematics. I no longer suffer from functions. Thank you دفعه ٢٠٢٢
Tutors at my school couldn't teach me this in over two hours what this video accomplished in 20 mins... thank you sir and thank god for UA-cam tutorials.
MR. Organic Chemistry Tutor, thank you for showing high school and college students How to Graph Trigonometric Functions the correct way. You are the first instructor that showed me How to Graph Trigonometric Functions the correct way.
First few mins in and I already understood a bit better thanks. My instructor in trig has been doing it for awhile and leaves vital info out during his lecture vids.
Today I did one of the questions on my exam that had the most points just by watching your video. Thank you very much for helping me and many other students, I can't explain how grateful I am:)
I am taking a trig course this semester, and I learn more from these videos that I do from my professor or her handouts. This channel teaches me all I need to know to get my assignments done in less time than the lectures or any hand outs/reading!
thank you for sharing your knowledge, i watched this before taking my precalc quiz this morning and i got a 100. this by far is the toughest unit yet and i couldn't have gotten through it w/o your help
For anyone wondering how he figures out the tick mark values on the x-axis: there are 5 critical points in the sin/cos cycle. Look at a one cycle of a cos/sin graph, and there will be 5 values: 2 values dictating the upper/lower bounds (y-axis values), and 3 values that will cross the x-axis (zeros). In order to find those critical point values (if you're dealing with a phase-shift), you find the value of the phase shift (0=Bx+c, solving for x), and then you add pi/2 recursively. For example, for y=sin(x+pi/3), the graph will start at x=-pi/3. Critical point #1 is -pi/3. To find critical point #2, -pi/3 + pi/2 = pi/6. To find critical point #3, pi/6 + pi/2 = 2pi/3. And so on until you have 5 values. You can use a calculator to add everything to make it easier. if you're still having trouble, google LibreText Mathematics section 2.4 on Phase shift.
To Sum Up: For equations y=a sin(bx) and y=a cos(bx), |a| is the highest y value point on the graph and -|a| is the lowest y value point on the graph. |b| represents the frequency of the graph or 2pi/b
There's nothing "video" here. The half-wit has entirely missed the opportunity to use a visual medium to show why these trigonometric ratios take the shape they do -- because radii stay th same while the other sides of the triangles involved vary. Just a horrid, stupid, ignorant waste.
There is 2 at the middle. Its just cause the amplitude is 2 he shifted the graph 2 units up and down from 3 which will bring us to the numbers 5 and 1 respectively.
Stock can drop from top to bottom and still be a 60 bagger. All this in 10y. investing is a very long journey where our temperament gets tested. have to have the capacity to suffer for long periods. have lived through the examples above, naming the stock today is pointless.
I'm here because the OpenStax course is letting me down when it comes to this particular subject. Algebra and prealgebra were fine except when explaining how to sketch functions or derive them from a graph, and with trig it's just awful. Just listing formulas, skipping steps, no explanations. EDIT: yeah, this guy's explanation is so much simpler. Such a simple step-by-step to construct a graph with phase shift. The OpenStax textbook makes this so needlessly complicated.

But why change it to 4 pi over 2 instead of leaving it as 2 pi in the second last question y=sin( x - pi/2)
I'm in my early 40s and just started college. You are doing the lord's work.
Excellent example of age is just a number

Boutta fail my pre calculus exam 🔥🔥🔥
How was it?
He failed……
:((
How was the test?
What is Andrew tate start teaching calculus
I love you. I spent two hours in my precalc lecture last wednesday absolutely oblivious, you made this so easy to understand. Thank you so much.
I have my term final tomorrow and part of it dealt with cosine and sine functions. You are a life saver, I didn't understand this until just now
I’m literally speechless of words to praise you of your knowledge+your aptitude of explanation.
A real life saver.

@@L2.Lagrange yeah, people need to grow up. Ik that he must be liking his maths professor who sleeps in the class and teaches nothing.
wish my dad would do the same
wish I have a dad
THANK YOU! I literally have a test on this tomorrow you are the best teacher!
Brilliant breaking down of trigonometric Graphing
Really Helpful Thank you very Much!!
mr. tutor you are an absolute lifesaver, thank you, I felt like I was gonna tear my hair out when I was trying to answer this
this made so much sense to me thank you so much for this! i have a placement test coming up and I'm so scared, thanks again!
Your videos are so simple and easy to understand ❤
Sir you're the best.....
I love you so much ❤️. And wish I could even recognize you 🤧🤧😫
You made me pass my. Exam I failed twice😫😫😭😭
I tried many yt videos and it was all confusing until i came to yours. Thank you!
You're the goat 🐐 better than my maths teacher
This video was so helpful, thank you so much!
Spent an hour trying to figure this out based on the book and modules our teacher provided but this video taught me in less than 7 mins
I don't get it at the level of 15:15 because of the graph extending to 4pii and why is the negative y-axis is upto -3 .
I love you so much man
I could not understand a thing about drawing trig graphs in class.
You are amazing
It’s an honor being the first person to watch one of your videos.
Thank you so much for your videos 🙏 You really saved me for my math and chemistry exams☺
Dude you just saved my life on a project, thank you so much
best video I have found on this topic... last minute panic before my IB exam :D
You are the true Math Hero
thank u, im struggling studying for my midterm and this helps sm
Sir, your teaching style is so awesome
Thank you so much! You helped heaps, for some reason I don’t understand anything my teacher is saying ;(
Thank you for what you do 🥹
bro is so good... thanks for saving my grades again!
I'm very lucky because I found your channel.
You are carrying me through my pre calc course like Joe Burrow taking the Bengals to the Super Bowl.
This is the smartest man who ever lived and who ever will like literally people think I'm some kinda STEM queen but it's all this king
Thank you,You have helped me a lot.
YOU ARE MY LIFE SAVER
Thank you!
This helped so much! Thank you!
Thanks much💯
Love you sir❣️
Hi,just wanna enquire act y do we put pie values and not actual real values such as 90,180,360 and so on🤔
Nice Explanation
Thanks alot
I am Egyptian but I like your explain it is so simple
♥️♥️♥️♥️
Hello incase you need help in online classes,assignments and tasks ,I'm here to help you out.
What's the period of the function y= sin x + cosx???
This helped me so much!! Thank you!
What is your specialty.? Engineering?
Keep on moving sir 🙋🙋🙋
Thanks for the video!
Who taught this guy?! This guy knows everything in maths, chemistry and physics!!!
dude you saved my life
It really helped thanks bro❤
amazing!
this helped so much
lets gooooo!!! crazy with math!!!
Thank you so much bro 😊
Thanks
You the best Sir we love you
Saved my life
thank you so much! God bless
I wish you were my maths teacher.
The equation is y=Asin(Bx-C)+D
thank you so much, this helped a lot :)
Very helpful thanks sir
How did you get 3pie/2? 19:07
thank you so much 🎉❤
At 21:50 the number in between 5 and 1 should be 3 on the y-axis of the graph.
There is 2 at the middle. Its just cause the amplitude is 2 he shifted the graph 2 units up and down from 3 which will bring us to the numbers 5 and 1 respectively.
thank u my king
The best video
Mistake at 21:48 it should be 5 pi/2 not 4. Great Video regardless.
Thanks alot
Thank you
may you have a good life

Reason why everyone should have a profitable investment.people need money
You're right Investment is the key to surviving during times like this when the government decided to mess with people.
Yeah what type of Investment y'all are into the stock market has been crashing lately.
Bitcoin investment is the best when you're on a profit based platform especially with the current rise.
Investing in cryptocurrency and gold which is better?
Thanks Mr, but that function of y=2cos(x)-1 the period is in 360 degrees, or am I confused.
you can also think of B as the number of cycles within a length of 2π
Now let's talk about..
graphing..
..TRIGONOMETRIC FUNCTIONS.
Amazing
at 17:45 isn’t the general form of sine function is asinx(bx-c)+d?
No it is + c

Wooow thanks
Thanks big dawg🫡
how does 2pi divide 1/2 = 4 pi
EOC next week wish me luck guys
I wonder why there is a person disliking this..
I think, the people who disliked this video are our professors who always fail to teach us smth properly💀
Tqq
I'm absolutley speechless .
