Along with that I observed that sin (Θ-pi/2) = ( sin (Θ+pi/2) / cos (Θ+pi/2) )Hi, since the trigonometric functions are periodic there is more than one answer to what 3x can equal to sole your equation. sin(v) = 1 implies v = pi/2 , but but pi/2 + 2*pi or pi/2 + 4*pi will do as well since it is 2pi-preiodic. k represents any number, that is k = 0,+-1,+-2,+-3 etc.This is because $5\pi/6$ is not in the domain of the truncated sine. If we start with an angle between $-\pi/2$ and $\pi/2$ then the arcsine does reverse the sine: $\sin(\pi/6)=1/2$ and $\arcsin(1/2)=\pi/6$. What is the derivative of the arcsine?
