Sketched below are four regions. Determine, with reason, which of these regions have equal area.

( "My calculator told me" doesn't constitute a good reason: if you believe two areas t o be equal, you

should show that they exactly equal.)

/ ( Problem 2 1 [More Than One Way]

In an example from class we used integration by parts t o compute the indefinite integral 1 cos2 B dB.

Find an alternative solution that makes use of the trigonometric identity

cos(28) = 2 cos2 0 - 1.

Make sure your answer is the same as the one from class.

/ /Problem1 1 [integration techniques in the abstract]

(a) Suppose you know that J: f (t) dt = a , where a is a constant. Calculate each of the following definite integrals:

(b) Let f be a twice differentiable function such that f (0) = 6, f (1) = 5 and f l ( l ) = 2. Evaluate the

definite integral f i x f1/(x) dx
