    It's 5pi/6.-----The inverse function of a function is the original value. However, it could also be other values, as sine functions are cyclic. sin(5pi/6) = 0.5 sin-1(0.5) = pi/6, 5pi/6 (as principal values) To be thorough: = pi/6 + 2n*pi, n = 0,1,2,... = 5pi/6 + 2n*pi, n = 0,1,2,...

    4[cos (pi/3) + i sin (pi/3)] and z_2 = 2[cos (5pi/6) + i sin (5pi/6)] are complex numbers, find z_2 - z_1. I have to write them in rectangular form, and I don't know how. ~~~~~ z = 4(cos (pi/3) + i sin (pi/3)). You probably know that cos(pi/3) = and sin(pi/3) = . Substitute it in the formula for z. You will get z = = . That's all with this case.
