The following sum

is a right Riemann sum for a certain definite integral

using a partition of the interval http://webwork.umemat.maine.edu/webw...89969e0f31.png into http://webwork.umemat.maine.edu/webw...70877535c1.png subintervals of equal length.

Then the upper limit of integration must be: http://webwork.umemat.maine.edu/webw...dd497c3d61.png =

and the integrand must be the function http://webwork.umemat.maine.edu/webw...910e13a9c1.png =

can someone help me with this
