Evaluate the integral 1 integral13 dxx2 100 x232 Using the
Evaluate the integral 1 = integral_1^3 dx/x^2 (100 - x^2)^3/2 Using the Romberg Integration up to 32 segments. Using Gauss-Legendre quadrature with different number of gauss points (2,3,4). Given that the exact vale of the integral is 1 = 1/100 [- squareroot 100 - x^2/x + x/squareroot 100 - x^2]_1^3 Compare the approximated results by finding the error in each case
