just a couple problems i need some help with.
1. Find the measure of the angle in radians and degrees.
2. Find the six trigonometric values of theta= cos^-1 (3/7). Give exact answers. I remember doing this during the school year but it's been a long summer and i've competely lost touch with this topic unfortunately (Worried)
3. Solve for x: e^-0.2x = 4
