| Question 216682:  find the value of sin^-1(sin 5pi/6)

You can put this solution on YOUR website! 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,...
