Sine and cosine — a.k.a., sin(θ) and cos(θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio of the adjacent side to the hypotenuse .
Which side is sin and cos?
Let us start with some definitions. We will call the ratio of the opposite side of a right triangle to the hypotenuse the sine and give it the symbol sin. The ratio of the adjacent side of a right triangle to the hypotenuse is called the cosine and given the symbol cos.
How do you know if its sin or cos?
The sine of an angle is equal to the side opposite the angle divided by the hypotenuse. The cosine of an angle is equal to the side adjacent to the angle divided by the hypotenuse.
