Calculus study - The study of change mathematics that has two main branches: the differential calculus (about the rate of change and the slope of the curve), and the integral calculus (concerning the accumulation of numbers and areas below and between the curves ); these two branches are related to each other by the fundamental theorems of calculus.

Cathode - An electrode in which an electric current flows out of a polarized electrical device. The direction of electric current is, by convention, opposite to the direction of electron flow. Therefore, electrons flow into the polarized electrical devices and out of, for example, connected electrical circuits.
