How do you solve complicated trigonometry questions?

You make them less complicated by using trigonometric relationships and identities, and then solve the less complicated questions.

How can you get into calculus?

Typically, the pre-requisite for calculus is algebra and trigonometry. These are usually universally required because you need these skills to actually do the mathematics of the calculus. There are a lot of identities in trigonometry that you will wish you could remember when you are working with calculus of trigonometric functions.

What is the definition of proving identities?

It means that you prove that an equation is true for ALL values of the variable or variables involved.

Does sin squared x plus cos squared x equal 1?

What are the identities in trigonometry?

Sin2x + Cos2x=1, so Cos2x=1-Sin2x and Sin2x=1-Cos2x. Also Sin/Cos = Tan. Sec2x=1+Tan2x. Cot2x+1=Csc2x.
