What are the basic trigonometric ratios?

Back

Sine (sin), Cosine (cos), Tangent (tan).

Front

Define Sine (sin) in terms of a right triangle.

Back

sin(θ) = Opposite side / Hypotenuse.

Front

Define Cosine (cos) in terms of a right triangle.

Back

cos(θ) = Adjacent side / Hypotenuse.

Front

Define Tangent (tan) in terms of a right triangle.

Back

tan(θ) = Opposite side / Adjacent side.
