36. The following limit is the derivative of a composite function g at some point x = a. cos(It / 12 + h) - cos (12/ 144) lim h - 0 h a. Find a composite function g and the value of a. b. Use the chain rule to find the limit. a. g(x) = a = (Type an exact answer using it as needed.) cos(7 / 12 + h) - cos (12/ 144) b. lim h -+ 0 h (Type an exact answer using it as needed.)
