Cos ni nini?
The cosine function (cos) is the ratio of the adjacent side to the hypotenuse in a right triangle, or the x-coordinate on the unit circle. Cosine is the "horizontal component" of an angle, while sine is the vertical component.

- adjacent / hypotenuse — adjacent / hypotenuse
Mwongozo wa Hatua kwa Hatua
- 1In a right triangle: cos(θ) = adjacent / hypotenuse
- 2On the unit circle: cos(θ) = x-coordinate at angle θ
- 3cos(θ°) = cos(θ × π/180)
- 4Key identity: sin²(θ) + cos²(θ) = 1 (Pythagorean identity)
