Find [ 5 9 f ( x ) d x if 105f (x)dx = -6 and |09f(x)dx=5 159f (x)dx= i Evaluate the integral by completing the square and applying appropriate formulas from geometry. NOTE: Enter the exact answer. Express the integral in terms of the variable u, but do not evaluate it. [1lav15 - 12 da; u = 15-2 NOTE: Enter the exact answer. Make sure the integration limits are in increasing order. 1lav 15 - 8 da = 2 Vu du Evaluate the definite integral by expressing it in terms of u and evaluating the resulting integral using a formula from geometry. sinov9-36 cos 0 do; u = 6cos 0 NOTE: Enter the cract answer. sinov9-36 cos3 0 de =
