Introduction to Using Trigonometric Identities (Precalculus - Trigonometry 23)
Показать описание
A quick look at Trig Identities and how to use them. Basic identities such as the Pythagorean Identity, Reciprocal Identities, and Even/Odd Identities are explored.
I don’t even need to watch this. Just dropping by to show some love. You took me through Calc 1, 2, and 3. Forever love you man!!

Professor, You've taught me calculus and Differential equations. Its time you teach me the arm routine.

I Love all Leonard videos. I wake up in the morning. Do some Bible Study, followed by a Leonard video and I’m ready to take on my day… 😇 Best Math Videos Ever!

Greetings from Sweden.
The statistics series is a complete life saver. Came in here just to show appreciation for your craft sir.
You look like Clark Kent but you're even better. He's using his powers for good. You bestow your superpowers upon others.
Thank you for everything you do sir.

Thanks for the helpful video, studying for a Precalc final.

Professor Leonard, thank you for a short and sweet video/lecture on the Introduction to Using Trigonometric Identities in Precalculus. Transcendental functions and their identities are very important in Mathematics, Physics and Applied Engineering. In the final example, equal signs are missing.

Your channel should be called “Math Chad”

From Iraq, we are studying this in the last stage of study and it is fun to study with an English teacher instead of an Arabic one to kill two birds with one stone, learning English and learning mathematics. 😅😊❤

i have a few friends who were considering changing streams, they took science, and wanted to go commerce...then the best coincidence occurred and i found your channel...sent them the links to your videos, their reaction was "where was he? dude where was he? why do we find stuff out late? although that's better than never finding the it, but dude, where was he?"

i watched this video and at 21:07 i did the problem differently and would like to know if it was a option, or did i just get lucky when i came out with the right answer. Instead of factoring i split it in to 2 fractions. cos(sqrd) over cos(sqrd) and - 1over cos. help.. lol... i later followed your video and did it the way you did it and got the same answer. Just luck? Thanks.. love your videos.. happy to support your channel..
