Reciprocal Identities

Additional Resources:

In this lesson, we will learn about reciprocal identities in trigonometry. All trigonometric function values can be found by taking the reciprocal of another function value. sin θ and csc θ, cos θ and sec θ, and tan θ and cot θ are reciprocals. Additionally, we will learn about the signs of function values. Lastly, we will learn how to find the values of all six trigonometric functions given one value and the quadrant.
