We'll its been a while since we've done blog posts so we've learned quite a bit since the last blog. The main thing we've been doing recently is definite integrals. Before we did that, we did the whole concept of using rectangles to find the area under the curve of a function. Using more rectangles is more accurate (obviously). To get a perfect area you'd want to use infinite rectangles, so that's were limits come in. There's this long sum notation thing that equals the integral notation. We did a big long proof which was kind of confusing but kind of made sense. We then learned how to actually solve define integrals by hand which luckily was much easier then the crazy proof. As of right now, I can do all the things we've done so far but I don't completely understand it. I'm basically just following the steps. I don't get how the inverse derivative relates to having infinite amount of rectangles. But I'm pretty sure it will click more as we do it more, which is what usually happens in math if it doesn't make complete sense at first.
