I have a couple of questions. My prof is having us do a chart. It's of sin, cos, tan, cot, etc functions. You're given one and have to get another.
One of the ones I am stuck on is as follows.
You're given Sin theta and need to get Tan theta. I think I need to use a Pythagorean Identity to prove it. Here's what I did...
Sin theta to Tan theta
Using the ident. Cot squared theta + 1 = Csc squared theta
Then I used the Reciprocal Idents. to get 1 / Tan^2 theta + 1 = 1 / Sin^2 theta.
Then 1 / Tan^2 theta = 1 / Sin^2 theta - 1
That's where I'm stuck... What do I do next?
