I am having problems with solving the integral for parts C and D if you could help. See copy pasted full question 1.25. The book information is also below. Also see attached figure. The chegg solution doesnt explain good enough. I attached the chegg soluiton with with the part I dont understand circled in red.

1.25 The voltage and current at the terminals of the element in Fig. 1.5 are

v = 250 cos 800pt V, i = 8 sin 800pt A.

a) Find the maximum value of the power being delivered to the element.

b) Find the maximum value of the power being extracted from the element.

c) Find the average value of p in the interval

d) Find the average value of p in the interval

See attached for Fig. 1.5
