Let us begin with the simplest- the reciprocal identities.
So, an example of using this would be:
There are also the quotient identities.
And last but not least are the Pythagorean Identities!
We proved the first one in class, so here is the proof of that along with the other identities:
And where the trigonometric functions are negative or positive:
Alright, that's it! Sorry this took a while, I didn't get the e-mail for the blog!
