Answer 1

Sine, Cosine and Tangent are the three main functions in trigonometry.

Explanation:

They are often shortened to sin, cos and tan.

To calculate them:

Divide the length of one side by another side.

In picture form:

For a triangle with an angle θ, they are calculated this way:

Sine Function: sin(θ) = Opposite / Hypotenuse
Cosine Function: cos(θ) = Adjacent / Hypotenuse
Tangent Function: tan(θ) = Opposite / Adjacent
