(a) The integrand of each definite integral is a difference of two functions. Sketch the graph of each function and shade the region whose area is represented by the integral.
\(\int_{0}^{1}(1-x) d x \quad \int_{0}^{1}\left(x-x^{2}\right) d x \quad \int_{0}^{1}\left(x^{2}-x^{3}\right) d x\)
(b) Find the area of each region in part (a).
(c) Let \(a_{n}=\int_{0}^{1}\left(x^{n-1}-x^{n}\right) d x\). Evaluate \(a_{n}\) and \(\sum_{n=1}^{\infty} a_{n}\). What do you observe?
