5.) Differentiate y = cos\" i -sin' i. ii.) Find the area bounded by the paraboiasy =iSJu:;r2 nutty: .111 2x. Sketch the graph. T.) A boy is ying a kite at a height of 150 it. If the kite moves horizontally away from the boyr at 2i] iseo, how fast is the string being paid out when the kite is 250 ft from him? 3.) Find the volume generated when the plane area bounded by y = x2 3x+s and x+y=0 is revolved [a] about I = 3. {b} about '3! = 1}. Sketch the graph
