Provide an appropriate response.Graph f(x) = cos-1 
and g(x) = tan-1 
. Explain why the graph looks like it does.
What will be an ideal response?
When x is positive these graphs are identical because they are both giving the same angle. 
When x is negative both functions are still referring to the same angle. However, inverse cosine gives values between ?/2 and ? while inverse tangent gives values between -?/2 and 0.
