Integration using Computer Algebra Systems (CAS): Example 1

In this video I go over an example on using computer algebra systems (CAS) and use an online CAS to solve the integral of the function x(x^2+2x+4)^(1/2). This was the same example I had solved earlier using tables of integrals and that video can be seen in the video links below. The resulting answer from both the tables of integrals and the online CAS appear different at first but I show that this is common and both can be rewritten so that the answers are identical in form. Also in this example I show that sometimes when rewriting the answer to another, there may be an additional constant appearing in the answer but since it is just a constant it can be absorbed into the all-encompassing constant of integration. This is a very important video to watch for those that may have questions about why a computer produces different answers than if they were to integrate by hand!
