How do you figure out cos and sin?

this is all i can give you

Explanation:

1.The sine of the angle = the length of the opposite side. the length of the hypotenuse.

2.The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.

3.The tangent of the angle = the length of the opposite side. the length of the adjacent side.

In a right triangle, you always want to use the right angle as a reference. Sin is opposite side over hypotenuse, and cos is adjacent side over hypotenuse. An easy way to remember is SOHCAHTOA (Sin Opposite Hypotenuse, Cos Adjacent Hypotenuse, Tan Opposite Adjacent), The acronym I use to remember this is "Some old hippy caught another hippy tripping on acid."
