Reviewing the basic integration techniques. A blast from the past. The easiest thing for me was definitely u-substitution, its easy for me to recognize and usually the first thing I try anyway. The hardest thing is probably noticing the common trig integration (arctan, arcsin, etc.), because I usually start to approach it in a different way before I realize how easy it could've been. Also it's hard to remember u/a and absolute value of u/a and all of that stuff

We reiviewd the Differential Equations unit today. The hardest part for me is utilizing Euhler's method. I usually take much much longer than most people and am not very handy at using it on a calculator. An easier part for me was the actual defferentiating, such as isolating each set of variables and moving them with the respective dy or dx, etc. So the basic differentiating and Anti-differentiating was easiest for me.

Series was nice day for me, I seemed to remember that unit much better than the others and was able to quickly work through all the example problems. I would say that nothing was particularly hard for me today, I remembered the different techniques, methods, and of course DO NOT do nth term test for convergence.

Reviewed Taylor Polynomials. One thing that was surprisingly difficult for me was remembering the common taylor polynomial power series such as cos(x), sin(x), e^x, and ln(x). I had completely forgotten them, though I think the review jogged my memory. The easier part was applying the common taylor polynomial formula to any equation, I usually work through that rather quickly. That is sum[f'(x)(x-c)^n] n!.

Reviewed the advanced integrationt techniques. Parts was easaier than I remember, and tabular was rarely used
-
Practiced LeGrange, feel much more confident and ready to take the test
-
wasn't in school, had APCS exam
-
Felt really good about it. No LeGrange, very little polar
-
Out of school for AP English Exam
