Evaluate the integral. e38 sin(48) de Step 1 We will begin by letting u = sin(48) and dv = e39 de. Then du = sin 46 130 4 cos(40) de and v = 3 3 Step 2 After integration by parts we have e39 sin(48) de = sin(40)e3 4/3 'sin(40) 4/3 e39 cos(40) de- 3 Step 3 We'll now apply the integration by parts procedure to the new integral / e39 cos(48) de, letting U = cos(48) and dv = e39 de. Then du = de and V =

Sand is being dumped from a hopper railcar at a rate of 40 cubic feet per minute. It forms a pile in the shape of a right circular cone whose base diameter and height are always equal to each other (both are growing larger as more sand is dumped). How fast is the base diameter increasing when the base is 18 feet long? Round your answer to three decimal places. ft/min
