I'm David Chedester. I'm a Junior High School Student who loves to do math, even for fun! I may not know advanced subjects, but I do know quite a bit about the Lambert W Function, Limits, Derivatives, and a lot about algebra and a bit of set theory (about aleph-null specifically). Here's an integral to solve for fun!

$$\int_{0}^{\infty} \frac{2x\sin(x)}{\cos(x)}$$
