This is the for the blog that was supposed to be done before this weeks. I have no clue what week we are on anymore. We learned how to do u substitution for definite integrals. Pretty much its the same thing as with indefinite integrals except you have to account for the upper and lower bounds. It's easy and all you have to do is plug it into whatever you made the u. Also I thought it was kinda interesting how there's to different ways to do it. We didn't talk about it in class, but on one of the assignments a problem near the end talked about it and showed it. Basically, instead of plugging in the bounds to the u, you just plug the u back in to the formula after you integrated it. This seems more intuitive to me, but I'm guessing it is more work to do usually, or we probably would have learned it.
