1. The problem statement, all variables and given/known data Is there a derivative of cot^-1x 2. Relevant equations 3. The attempt at a solution so far i used the inverse property to detemermine that coty = x then i used the chain rule to get -csc^2y * dy/dx = 1 and i isolated for dy/dx dy/dx = 1 / -csc^2y what now??
