What is the Tangent Calculator?
The Tangent Calculator is a fundamental trigonometry tool used to find the tangent value of a specific angle. It is widely used in physics, engineering, and architecture to calculate the slope or steepness of a physical structure.
How It Works (Formula)
In a right-angled triangle, the tangent of an angle ($\theta$) is mathematically defined as the ratio of the length of the opposite side to the length of the adjacent side. In terms of other trigonometric functions, it is Sine divided by Cosine.
$$ \tan(\theta) = \frac{\text{Opposite}}{\text{Adjacent}} = \frac{\sin(\theta)}{\cos(\theta)} $$
The fundamental trigonometric identity for Tangent.
How to Use It
First, select your preferred unit of measurement (Degrees or Radians). Enter the value of your angle, and the calculator will instantly output the precise tangent ratio.
