Substitution in the Indefinite Integral Part 1. Suppose that you want to re-write an integral using a substitution, in this case, st 4x11 + 8x2 dx = 212 + 8.73 1 34. du Determine the correct substitution that will accomplish this. That is, find u as a function of x that allows you to re-write the integral as shown above. The function u(x) we want is in which case the differential of u is Note: answer should be in the form u= f(x) and du = f'(x)dx Part 2. Evaluate the indefinite integral above in terms of u. 1 du Зи Note: answer should be in terms of u only Part 3 Back substituting in the antiderivative you found in Part 2. above we have 4x11 + 8x2 dx 212 + 8.73 Note: answer should be in terms of x only
