This week in AP Calculus, we learned U Substitution for definite and indefinite integrals. This week was not all that difficult as it was just a combination of topics that we have learned throughout the year. We basically are taking what we learned the last couple weeks, and applying the concept of U Substitution to it. By using U Substitution, it makes evaluating the integral easier as you are replacing part of the function with just a variable. I believe that this makes doing these problems without a calculator so much easier. The one new part of this that we learned was how to find the bounds when using U Substitution. We did an exploration on it and I think that it really helped explain why the bounds changed. Other than that, everything was review of topics or combining old topics with new topics. We also had a Chapter 5 test this week that I did really well on. Me understanding integrals really helped me this week because you need to have a good understanding of the basics before you can jump into the difficult things.
