Simplifying Trigonometric Expressions Using Identities, Example 3

[DrBeef]

I find these sorts of vids essential for really learning everything in University Pre-Calc, and will continue to utilize them all the way through Calc 3. They make home studying so easy.

It must've sucked to have a lousy professor in, say, the 1960's...

My math teacher never taught us this in class & told us to go learn it at home by yourselves. So I've came in TWICE during MY LUNCH for help like a responsible student. She was absent those days and expects to take a quiz on it tomorrow. THANKS SO MUCH FOR HELPING. (to patrickJMT, not sarcastically to my horrible teacher)

PRAISE YOU FOR SUCCESSFULLY TEACHING ME THIS

[shaunmoloi]

at this point i have ran out of words to thank you. Truly amazing stuff!

[MicroTex]

Keep posting Patrick..love all your videos and I just want to say you are changing lives in such a profound way!!!

[randomchikk]

Ahh I have a test tomorrow... How much I wish you were myteacher.
I love how you could basically find anything you need on youtube:)
Thank you PatrickJMT

I didn't know you could manipulate the identities like you did. Thanks!

At 2:21, you said "Let's deal with the numerator first", while you were pointing at the denominator, which is what I think you meant to say.

You are literally going to save me from failing Pre-Calc. Subbed.

Hi, I just wanted to say so far I've really enjoyed and found your videos an excellent compliment to reinforcing concepts I've been studying. I was watching one video, particularly the simplifying trig expressions using identities, and I noticed a combination of use of x and theta--may I assume you simply use those interchangeably, or did I miss a statement on it in a different video? Thanks in advance!

If only you knew how many times you've saved me!!

[DrappaWolfy]

This was a very helpful video. Thank you for posting!

[Kniitte]

OMG I LOVE YOU <3 i was so stuck on this in class recently xD

[Bosley]

Very awesome! I think you just saved my Pre-Cal grade! :D

[m.j.]

At 3:06 you say we want the CSC to remain positive, why is that?

[mosheweinfeld]

Pretty much what everyone else is saying, you saved my ass.

[MuneerShaikRiyadh]

Sir can u plz make a video on sin squaretetha and costetha relation.

[powerserge]

Yeah, the theta and x really doesn't make a difference in the problems. They're pretty much the same thing when dealing with simplifying trigonometric expressions

[al-raufhkanakan]

At letter e? sir im little confused wth the solution, my answer for that is 1
^_^ can u reply ? thank you .

[FerFerrrrr]

thank u very much, it helps me a lot, god bless u! <3 :'(
