1. The problem statement, all variables and given/known data f(x)= x+cosx find the inverse, f^-1(x) 3. The attempt at a solution To start, I tried to solve the original equation for x. But this is where I am having trouble. How do you get x by itself when it is trapped within the cos function? I used to know how to do this but I seem to have forgotten. Once I solve the equation for x, I should be able to switch the "x" and "y" terms and be left with the inverse of the original function. Maybe someone can help me remember how to get the 'x' by itself. Thank you.
