It's basic calculus.
I'm not too sure if 'basic' and 'calculus' sit too well together 
Compared to what I learned, and have since forgotten in calc 2 and 3 it is
basic. If you want to see a course that makes sanity seem like an illusion try
one in imagionary variables.
Algebra is when you stop counting on your fingers and start using your toes.
Calculus is when you tie those toes in knots. Differential equations is when
you start learning you are now different..........etc.
