this was a question on a calc test.

Let F(x) be the antiderivative of f(x) = (x^2) cos(2x) and F(1) = 0

a) find F(x) and F(3)

b) find the critical values of F(x) in [0,pi]

c) find F''(x)

d) For the values you found in b), explain which (if any) are local maxima. Justify your answer.

e) Find the absolute maximum value of F(x).

now these questions are pretty straightforward and easy but the problem i have is that there is no graphing calculator allowed on this test. i answered a,b,c, and, d easily, but e) is giving me some trouble. i found the local max at 3pi/4 and the two endpoints 0 and pi i have to test as well by plugging back into F(x). now this test was before we learned integration by parts so we can't use that technique. so the only way to find F(x) was to use the fundamental theorem of calculus so that F(x) = integral (from 1 to x) of (t^2)cos(2t) dt and evaluating F(x) means evaluating the respective integrals. the problem i have is that i don't know how to evaluate these integrals without a graphing calculator. My TI-84 has a program for evaluating definite integrals but the scientific calculators provided for us has no such function. how are you supposed to do part e) using only a scientific calculator?
