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.

  • Trigonometry(please Clarify) -

    The confusion arose because the term inverse function has more than one meaning in mathematics. So there was an answer for each interpretation of the term.

    However, if you are in the process of studying inverse trigonometric functions, such as arc-sine, arc-cosines, etc, your answers are correct.
