Question 1013466: Which expression is equivalent to sin(2theta) for all values of theta?
2cos^2(theta) - 1
cos^2(theta) - sin^2(theta)
1 - 2sin^2(theta)
2 sin(theta) cos(theta)
I believe the answer is the last option but I want to be sure. I believe it's the last option because it's the double angle identity for sin(2theta).
