a. Graph the functions f 1 (x) = sin 2 x and f 2 (x) = sin
Question:
a. Graph the functions f1(x) = sin2 x and f2(x) = sin2 2x on the interval [0, π]. Find the area under these curves on [0, π].
b. Graph a few more of the functions fn(x) = sin2 nx on the interval [0, π], where n is a positive integer. Find the area under these curves on [0, π]. Comment on your observations.
c. Prove thathas the same value for all positive integers n.
d. Does the conclusion of part (c) hold if sine is replaced with cosine?
e. Repeat parts (a), (b), and (c) with sin2 x replaced with sin4 x. Comment on your observations.
f. Challenge problem: Show that for m = 1, 2, 3, . . ,
