So I have a question that is:
Given that cos theta = 24/25 and theta is in Quadrant I, determine sin 2theta, cos 2theta and tan 2theta. Which quadrant is 2theta in?
I already solved the sin, cos and tan portion of the problem
sin 2theta = 336/625
cos 2theta = 527/625
tan 2theta = 336/527
but the issue I have is I have no idea how to determine which quadrant 2theta is in.
Any help would be appreciated! Thanks in advance!
