Assignment:
Qa) Find an approximation to the integral as 0 goes to 4 of (x^2-3x)dx using a Riemann sum with right endpoints and n=8.
Qb) Draw a diagram to illustrate the approximation in part (a).
Qc) Use this equation (the integral as a goes to b of f(x)dx=the limit as n goes to infinity of Sigma f(xi) delta x) to evaulate the integral as 0 goes to 4 of ((x^2)-3x)dx.
Qd) Interpret the integral in part (c) as a difference of areas and illustrate it.
Provide complete and step by step solution for the question and show calculations and use formulas.
