The last page contains some useful identities: (15 pts) find the indicated derivatives. No need to simplify. (a) (5pts) dx(ln (tan x)) (b) (5pts) dx(esin (7x)) (c) (5pts) dx(x5x: (10pts) find the indicated antiderivatives. Remeber +c! (a) (5pts) z ex cosh (ex) dx (b) (5pts) z. 1: (4pts) suppose the function f is one-to-one. Listed below are a few values of f and its derivative: x f (x) For example, f (0) = 1, f (1) = 4, etc. Fill in the blanks: f 1(2) = (f 1) (2) : (4pts) find a formula for the inverse of the function f (x) = x2 + 2x + 5, x > 1, (10pts) evaluate the following. Any answer representing an angle should be given in radians. (a) sin 1(
