I start solve some applied calculus tasks, but I dont really understand why for exmple second derivative represent acceleration, why first is speed, why I need to derivate Area=axb to find a and b with max area of recntangle if I know diagonal..etc

I know that differential is ratio of delta y / delta x. If I change x how much is change y, or simple tangent angle..

Can someone explain this?
