Here are a few derivatives that you should should memorize for Calculus 1. These are for exponential functions, logarithmic functions, trigonometric functions. You may or may not be given these in a Calculus exam, but you will certainly be required to know them and use them, so it is worth committing them to memory.

In circle geometry, lines that touch or cut through a circle reveal fascinating mathematical relationships. One of the most important among them is the secant line, which intersects the circle at two distinct points. Understanding how secants behave helps you uncover deeper geometric patterns, including how they connect with chords, tangents, and intersecting lines.
