Reciprocal Identities
Each of the six trig functions has a reciprocal partner. This guide shows the three reciprocal identities, how to use them, and the mistakes to avoid. Quick answer: The reciprocal identities pair each trig function with its flip: csc θ = 1/sin θ, sec θ = 1/cos θ, and cot θ = 1/tan θ. They […]
How to Graph the Cosecant Function?
The cosecant function is the reciprocal of sine where sine is nonzero. Zeros of sine correspond to vertical asymptotes of the cosecant graph. The cosecant function is the reciprocal of the trigonometric function sine. In this guide, you will learn more about the graph of the cosecant function. In this lesson Graph the Cosecant Function: what to […]
