Show all work to get full credit. Simplify your answers, when possible, but use the precise value rather than an approximation when you have a choice. (Example: If the actual answer is II, then write it, not 3.14.) 1. (15 points) Differentiate the following functions: 1) f (x) = * - 2 vx+ 3Vx ii) h(0) = e (tan0 + 0) COS X iii) f(x) = 1 - sin x
