This week we learned about definite integrals and antiderivatives. Which was pretty ok, despite the fact that it is making what we learned yet more complicated. To begin with we were given some simple rules. If you go from "a to b" and switch it to "b to a" for instance, the entire integral is made negative. also, if you go from "a to a" the integral is always zero. Most of the rules are pretty straight forward addition or multiplication. My favorite by far though is domination. Which has a really cool name, but is really lame in actuality. It means that if f(x) is greater than g(x) then the integral of f(x) is greater than the integral of g(x). Lame. It's like the cool looking foreign exchange kid in your class that has a fun accent and could be totally cool, but just likes to sit quietly in the corner and read comic books. A true tragedy.
We also learned about NINT, which made me miss Old Mac. Just plugging things in your calculator… those were the days.
The part that can actually get somewhat confusing is the anti derivative portion. I may or may not be a bit rusty when it comes to anti differentiating, so this is a nice wake up call. I also sometimes struggle with knowing when to anti differentiate or find the avg. value. I think on my quiz I confused those concepts a lot… which is disappointing.
