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.
