Due in recitation.
Make sketches of the calculator screen and hand those in when
called for. Be sure to indicate the axis scales on any sketch.

1.) Use the a graph of the integrand  to guess the value of
integral.  Then use the methods of integration to prove that
your guess is correct:
a.)  (cos(x))^3 from 0 to 2*Pi.
b.)  (sin(2*Pi*x)*cos(5*Pi*x) from 0 to 2.
c.)  (sin(x))^2 + (cos(x))^2 from 0 to 2*Pi.
d.)  (sin(x))^2 from 0 to 2*Pi.
e.)  (cos(x))^2 from 0 to 2*Pi.
