Calculus II (MAT 146)Dr. Day Friday August 30, 2013 • Questions: Integral Apps • Finish Volume Calculations and Applications (6.2) • Begin Chapter 7: More Methods of Integration • 7.1 Integration by Parts MAT 146
Review: Integral Apps (1) Calculate the exact value of the area between the curves f(x) = x3 – x2 – 2x + 1 and g(x) = x2 – 2x + 1. Show calculus and algebraic evidence for all aspects of your solution process. (2) Determine the average value of f(x) = sin(x) on the interval [0,π]. How many values ckexist, on [0,π], such that f(ck) generates that average value? Provide evidence for your responses. MAT 146
