What does sin and cost mean in math explanation. Best answer gets Brainliest

Sine (sin) and cosine (cos) are trigonometric functions that you can use with right triangles. The sine of an angle is the opposite side/hypotenuse and the cosine of an angle is the adjacent side/hypotenuse. You can remember these with the acronym SOH CAH TOA.

(Sine opposite hypotenuse, cosine adjacent hypotenuse, tangent opposite adjacent).
