Jinsi ya kukokotoa Sin

Sin ni nini?

The sine function (sin) is a fundamental trigonometric function defined as the ratio of the opposite side to the hypotenuse in a right triangle. It also describes the y-coordinate of a point on the unit circle at a given angle.

Fomula

In a right triangle: sin(θ) = opposite / hypotenuse
In
opposite / hypotenuse — opposite / hypotenuse

Mwongozo wa Hatua kwa Hatua

  1. 1In a right triangle: sin(θ) = opposite / hypotenuse
  2. 2On the unit circle: sin(θ) = y-coordinate at angle θ
  3. 3sin(θ°) = sin(θ × π/180) in radians
  4. 4Key values: sin(0°)=0, sin(30°)=0.5, sin(45°)=√2/2≈0.707, sin(60°)=√3/2≈0.866, sin(90°)=1
