- Im confused about what 1/arccos is equal too.

Im not sure what 1/arccos is. I looked online and all I have found is y=arccos(1/x) and I am not sure if that's the same thing. I tried to make a triangle to decipher the answer. However when I looked at the answer when I finished it was incorrect. I got 1/xsqrt(x^2-1) and the answer is 1/(arccos)^2 sqrt(1-x^2)
