(a) Use Trapezoidal Rule with n=8n=8n=8 to approximate the integral ∫01ex2dx\int_{0}^{1} e^{x^2} dx∫01ex2dx. Estimate the error involved in this approximation. (b) Use Simpson’s Rule with n=8n=8n=8 to approximate the integral ∫01ex2dx\int_{0}^{1} e^{x^2} dx∫01ex2dx. Estimate the error involved in this approximation.
