Show that the following relationships are satisfied by the given values:
sin2(theta) = 2sin(theta)cos(theta), when theta = 150 degrees

I'm just not sure how to answer this type of question.
Thanks

Next, substitute the angle on the RHS to find what the value is.

Acknowledge/check that they are indeed equal.
