cant figure this out for the life of me.

OpenStudy (yanasidlinskiy):

Sine, Cosine and Tangent are the main functions in trigonometry. The formula for sin: sin(θ) = Opposite / Hypotenuse

what is the formula for cosine?

OpenStudy (yanasidlinskiy):

It is cos(θ) = Adjacent / Hypotenuse And I think you want to ask what is the formula for Tangent Which would be tan(θ) = Opposite / Adjacent
