Section 5.3 - Volumes by Slicing
I can use the definite integral to compute the volume of certain solids. Day 2: a-dLet f be the function defined by Write an equation of the line normal to the graph of f at x = 1. b. For what values of x is the derivative of f, f ‘ (x), not continuous? Justify your answer. c. Determine the limit of the derivative at each point of discontinuity found in part (b). d. Can be completed using the method of u-substitution? If yes, complete the integration. If no, explain why u-substitution cannot be used for Solids of Revolution 7.3
