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!!!
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.
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 TH-cam tutorials.
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!!
tbh it's been a long time since I've last left a comment on yt, and you probably, deservingly, get this a lot.. but thank you. precal and genmath have been taking a toll on me these past few months, making me question my foundation of math concepts. but the way you teach makes it all seem so easy. the identity crisis i experienced was thru the roof, but ur videos are therapeutic in the sense that it reassures me that i can still catch up. i love you, ur doing the right thing. ur simple math videos are ur biggest legacy
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!
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.
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
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
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 don't know if people relate to this, but I pay attention in class, I study at home, but I still can't apply the knowledge properly. I must be intellectually inept or have inneficient studying habits
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.
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
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.
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.

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

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
Boutta fail my pre calculus exam 🔥🔥🔥
How was it?
He failed……

I literally watch your videos (especially physics) a day before any test or exam and get good grades, this is life saving, it helps so much.
This video was so helpful, thank you so much!
THANK YOU! I literally have a test on this tomorrow you are the best teacher!
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
It’s an honor being the first person to watch one of your videos.
I tried many yt videos and it was all confusing until i came to yours. Thank you!
Dude you just saved my life on a project, thank you so much
Brilliant breaking down of trigonometric Graphing
Really Helpful Thank you very Much!!
I love you so much man
I could not understand a thing about drawing trig graphs in class.

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!
You are carrying me through my pre calc course like Joe Burrow taking the Bengals to the Super Bowl.
best video I have found on this topic... last minute panic before my IB exam :D
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 .
So basically, -1 became the midline and as you can see, the amplitude is 2. Making it 1, 0, (-1), -2, -3.
bro is so good... thanks for saving my grades again!
thank u, im struggling studying for my midterm and this helps sm
Thank you so much for your videos 🙏 You really saved me for my math and chemistry exams☺
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😫😫😭😭
This helped so much! Thank you!
I'm very lucky because I found your channel.
Sir, your teaching style is so awesome
Keep on moving sir 🙋🙋🙋
Thank you,You have helped me a lot.
YOU ARE MY LIFE SAVER
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
Who taught this guy?! This guy knows everything in maths, chemistry and physics!!!
This helped me so much!! Thank you!
What is your specialty.? Engineering?
It really helped thanks bro❤
Thanks for the video!
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 i didnt know it was this easy, why cant i understand a single thing in my teacher!!
dude you saved my life
Thank you so much bro 😊
Thanks alot
I am Egyptian but I like your explain it is so simple

thank you so much, this helped a lot :)
Why is it so easy for me to understand you and so hard for me to understand my teachers?
this helped so much
Thank you!
How did you get 3pie/2? 19:07
the number between 1 and 2 is 1 1/2 which written as an improper fraction is 3/2
You the best Sir we love you
Thank you 😊 for helping me 😂😂❤
Dude needs to be protected as a international treasure.
thank you so much! God bless
lets gooooo!!! crazy with math!!!
why...why did this seem way harder in class? Thank you times infinity. may the Lord bless you!
Mistake at 21:48 it should be 5 pi/2 not 4. Great Video regardless.
Nice Explanation
I wish you were my maths teacher.
Very helpful thanks sir
Saved my life
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💀
Hi @TheOrganicChemistryTutor, just wanted to clear my doubt that will the graph of y=2sinx be the same as y=sinx +1.
You saved me thank you so much. And famous quote: “A cat can do trig”
Hi,just wanna enquire act y do we put pie values and not actual real values such as 90,180,360 and so on🤔
Now let's talk about..
graphing..
..TRIGONOMETRIC FUNCTIONS.
The equation is y=Asin(Bx-C)+D
thank you so much!
Thanks alot
yo this all what u need
at 17:45 isn’t the general form of sine function is asinx(bx-c)+d?
No it is + c
@@zayn-xw6runo its - c?
amazing!
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.
may you have a good life
thank u my king
Call on the Lord Jesus and you shall be saved
