An Indepth Look at Using Inverse Trig Functions (Precalculus - Trigonometry 21)

A very detailed explanation of Inverse Trigonometric Functions and how to use them in conjunction with Basic Trig Functions. Pretty much all you need to know about using inverse trig functions.

i love it when you say "i hope I explained it well enough". other teachers say stuff like "YOU don't understand" or "YOU're doing it wrong" and it's amazing seeing a teacher who understands a student's failure is a teacher's failure

[majeedfab]

No one really takes the time to talk about inverse trig functions like this video !!
Just thank you!

Hi Leonard! I'm just stopping by to say thank you for helping me pass my Differential Equation 2 semesters ago! I forgot to mention this back then, but I couldn't have gotten an A without your help! I hope you are doing well!

[summerlane]

I am sure I've thanked you before, but THANK YOU SO MUCH! Trig is really kicking my ass, but you are excellent at really explaining things in a way that makes sense in my brain. You are a life-saver. I wish I was taking an in-person class with you!

These videos do an amazing job of hammering in the information after just one watch. I am about to start calc 2 this summer, and reviewing tons of the pre-calculus videos. from inverse functions all the way to polar coordinates. I had a really bad pre-calculus teacher and never properly learned any of this stuff.

[philphymath]

Thank you so much, I cannot appreciate your hard work and generosity of time and spirit enough. Wishing you all the best

[mikedoeren]

You make learning math achievable and, dare I say, enjoyable. Thank you for helping me to learn to love math.

I sincerely hope you bring back your merch for purchase!

Thanks professor for your work...for your generosity...and for you being you....i used to hate math cuz of many variables...but after i took your calss in intermediate algebra i loved math and science...keep on doing the hard work sir...its for us and for you too...and i hope you get millions of subscribers and to always be well and healthy....thank you

[ojingaj]

BRAVO!!! Thanks for all your hard work Professor L!!

[macadonards]

This man is saving me in math god bless him

[anarchistds]

sir, pls complete this series as much as possible . but your work is so amazing.

Professor Leonard, thank you for the lengthy video/lecture on An Indepth Look at Using Inverse Trigonometric Functions in Trigonometry/Precalculus. The problems/examples are straight forward, however focus must be on the Domain/Range on all the Inverse Trigonometric Functions in order to produce correct solutions.

Thank you so much. My confidence level has has been become the range of Tan(x)
For the 58:43 Mark, I found (- pi/6) by using the cofunctions of Cot/Tan. Tan = Cot(pi/2 - theta). Since -pi/6 is in the restricted domain, I didn't have to think about the ratio.
Idk if you already covered that though.

[willpugh-calotte]

One special case of cot-1 that I was waiting to see if you would mention: cot-1(0), which = pi/2. You can't treat cot-1(0) as a Quadrant I case, because then you'd be trying to evaluate tan-1(1/0). If you draw the triangle to treat cot-1(0) as a cos-1 case in Quadrant II, the triangle will have a zero-length base and simply be a line extending up the y-axis from the origin, ie, at angle pi/2.

Professor Leonard your videos changed my perspective on math. Can you do a video on doing math for the skilled trades? Stuff that a would do. Or a video on mental math?

[mclarenp]

Am a 7th grader who watches these videos and I learn way to much XD

[hythe]

I wish you taught physics or there was someone like who taught physics

[hoangpham]

After 40 years, I see this video clip is brand new to me

[Shashank_Shahi]

How many more videos in this pre calculus series ?

[violethill]

why didn't we just make our own triangle when we find the angle for the inverse of csc and sec?
