## Homework Statement

If A= 30 deg.. verify that..
Sin2A = 2SinACosA
First off..On the left side where it says 2A... does that mean multiply 30deg by two? and on the right side does the two also mean multiply?

Anyways... since it is asking me to verify that they are equal... am i basically using the trig identities to prove that this statment is true by only working with one side and trying to make is look like the other side.?
