Root Explanation

Cosecant is formed from "co-" (meaning together) and "secant" (from Latin "secans", meaning cutting). In trigonometry, cosecant refers to the function that is related to the secant function, thus representing a relationship between the two functions in a right triangle context.

Memory Tip

Think of 'together' ('co-') and 'cutting' ('secant') to remember that cosecant is a function that relates to secant in trigonometry.
