Let R be the region bounded by the graphs of y=sin(pi x) and y=(x^3)4x, as shown in the figure above. (a) Find the area of R. (b) The horizontal line y=2, x=2, x=1. Write, but do not evaluate, an integral expression for the area.

MathMate,
Without a figure, it is not clear what R stands for.
Here's a plot of the functions. See if it is similar to the figure in your book/exercise. Describe the region R.
The question in part(b) seems incomplete, please check.
