# Integration

Please solve and explain.

Write the expression for the Riemann sum of f(x) = x^2 - 4x on the interval [0,8]

with n uniform subintervals using the right hand endpoints of the subintervals. Do not evaluate.

Using the Reiman Sum, write the definition of the definite integral 8 to 0 (x^2 - 4x)dx. Do not evaluate.

Using the definition of the integral above, now calculate 8 to 0 (x^2 - 4x) dx
