How to Use Inverse Trigonometric Functions (Precalculus - Trigonometry 18)

An in-depth look at how to use inverse trig functions and how they relate to basic trig functions. The domain and range of these functions is also thoroughly discussed.

I like how you repeat things over and over and over again. After awhile it begins to sink in and stays with you.

First 3 minutes are incredibly helpful. Master of your art Professor - not just knowing but explaining mathematics.

Thank you again so much for these videos. I would be failing math and considering giving up right now if it weren't for you. On top of that, the little motivational ways of saying "you're doing great" or the little bits of humor (The deadpan "Give me a value of sin of -2", "there is no -2 for sin", "I know") really have turned a nightmare of a semester into something I've stuck with. I wish more teachers were like you.

TY! U helped me understand inverse Trig SO much better! Probably the best explanation I've seen yet!..

[aurumstinger]

Fiirst time l am this early to your video, , , assuming and hoping you'll read this comment l just wanted to say thank you for each and every effort you have put in your work Sir, , you literally save lives and grades all at the same time . You're a super inspiration and l pray God blesses you with everything you deserve that's nothing short of good. I just hope l grow older to meet you one day <3 From South Africa *smiles* **

I've been done with school for a while, saw your vid in my feed and had to swing by! Thank you again for the help through all of calculus and Diff EQ!

Thanks for the videos! You helped me quite a bit in my precalc algebra class last year, so I am watching your trig videos this semester to assist with the class I am currently taking. :) you rock.

Professor Leonard, thank you for an excellent video/lecture on How to Use Inverse Trigonometric Functions in Precalculus/Trigonometry. I had some problems with the use of Trigonometric Functions in the past, however by paying close attention to the domain/range these functions operate in, I understand the inverse operations of these Transcendental functions.

Out of curiosity, roughly how many videos are left before this course is complete? Appreciate any response and it took one video from you on partial differentiation to make me want to take maths further! Legend.

[TheWorks]

do you create cheat sheets for each category? your videos are amazing you explain more than my own professors video. I understand you more great videos!!!

[inder]

Prof Leonard please please more differential equations videos 😭😭

[greymohan]

Hi Professor, I am following your precalc videos.. but would ilke to finish this before i start your calculus videos.. So would really like to know how many more videos you have in this series? :)

[wowyikes]

prof Leonard, could you enable one-time support or donation on your page?

[animeotaku-ttve]

sometimes i think i should just drop out and learn from

[Ensign_Cthulhu]

The use of the -1 superscript here is in my opinion a recipe for disaster. This is why we have arcsin, arccos, arctan, etc.

[roadchewerpe]

Do you / will you have videos on the half angle and double angle formulas? Is there really anything to know about them? Or should I just know them? I don’t like things that I just need to memorize and know.

I have always wondered when Professor Leonard was born.
He looks like he is maybe in his late 20s or early 30s in his first videos, so I guess he would be about 40 years old now in 2021?

Inverse trig functions = Reciprocal trig functions? Surprised!

[robichag]

Is that a unit circle in your pants, or you just happy to see me?
