Hi, if I have a piecewise function such as:
f(x) = (x-1)^2 if x>1
or tan(x) if -π/2 < x < 0
If I want want to find the inverse, do I simply calculate the inverse for each of piecewise operations ?
eg. (x-1)^2 has the inverse y = 1 +- sqrt(x)
and tan(x) has the inverse tan^-1(x)
is it is straightforward as that or I am missing something ?
thanks for any help.
