Front

Define secant (sec) in trigonometry.

Back

Secant is the reciprocal of cosine: sec(θ) = 1/cos(θ).

Front

Define sine (sin) in trigonometry.

Back

Sine is a trigonometric function defined as the ratio of the opposite side to the hypotenuse in a right triangle.

Front

Define cosine (cos) in trigonometry.

Back

Cosine is a trigonometric function defined as the ratio of the adjacent side to the hypotenuse in a right triangle.

Front

What is the relationship between sine and cosine?

Back

sin(θ) = cos(90° - θ) and cos(θ) = sin(90° - θ).

Front

What is the value of tan(θ) in terms of sine and cosine?

Back

tan(θ) = sin(θ)/cos(θ).
