Question

I posted ;

Write equivalent equations in the form of inverse functions for
a.)x=y+cos theta
b.)cosy=x^2

my answers were
a.)
x= y+ cos theta
cos theta = x-y
theta = cos^-1(x-y)

b.)
cosy=x^2
cos(y) = x^2
y = Cos^-1(x^2)

your post confused me a little. Can you clarify if my answers were wrong.
