To find theta
Consider a right-angled triangle, where the longest side is called the hypotenuse, and the sides opposite to the hypotenuse are referred to as the adjacent and opposite sides.
The six important trigonometric functions (trigonometric ratios) are calculated using the below formulas
- Sine Function: sin Θ = Opposite side/ Hypotenuse
- Cosine Function :cos Θ =Adjacent side / Hypotenuse
- Tangent Function : tan Θ: Opposite side / Adjacent side
- Cosecant Function: cosec Θ =Hypotenuse / Opposite side
- Secant Function : sec Θ= Hypotenuse / Adjacent side
- Cotangent Function: cot Θ = Adjacent side / Opposite side
The trigonometry angles which are commonly used in trigonometry problems are 0°, 30°, 45°, 60° and 90°.
