Summary
A trigonometric function of the inverse function of x written
inx , on the principal branch: cos(arcsin(x)) is
sqrt(1 - x^2) there, since the cosine is not negative on
[-pi/2, pi/2] ; tan(arcsec(x)) is x sqrt(1 - 1/x^2) , the sine
not negative on[0, pi] ; and the cosine of arccot(x) , whose range
here is(-pi/2, pi/2] , is |x|/sqrt(1 + x^2) . Whatever is not one of
these compositions, a multiple angle among them, is left as it is.
