Consider the region R {\displaystyle R} in the first quadrant bounded by the x {\displaystyle x} -axis and the curves y = x − n {\displaystyle y=x^{-n}} and y = x n {\displaystyle y=x^{n}} , where n > 1 {\displaystyle n>1} is a real number.
Find the volume V ( n ) {\displaystyle V(n)} of the solid generated by revolving R {\displaystyle R} about the x {\displaystyle x} -axis. Express your answer in terms of n {\displaystyle n} .
