Understanding Trigonometric Functions

Sine (sin)

The sine function represents the ratio of the opposite side to the hypotenuse in a right triangle.

$\sin(\theta)=\frac{\text{Opposite}}{\text{Hypotenuse}}$sin(θ)=HypotenuseOpposite​

---

Cosine (cos)

Cosine represents the ratio of the adjacent side to the hypotenuse.

$\cos(\theta)=\frac{\text{Adjacent}}{\text{Hypotenuse}}$cos(θ)=HypotenuseAdjacent​

---

Tangent (tan)

Tangent is the ratio of sine to cosine.

$\tan(\theta)=\frac{\sin(\theta)}{\cos(\theta)}$tan(θ)=cos(θ)sin(θ)​
