What is the Tangent Calculator?
The Tangent Calculator is a core trigonometry tool. It determines the tangent of a specific angle, which represents the steepness or slope of a right triangle's hypotenuse. It is heavily used in physics and architecture.
How It Works (Formula)
In a right-angled triangle, the Tangent of an angle is mathematically defined as the length of the Opposite side divided by the length of the Adjacent side. It can also be expressed as Sine divided by Cosine.
$$ \tan(\theta) = \frac{\text{Opposite}}{\text{Adjacent}} $$
The standard trigonometric definition for Tangent.
How to Use It
Select your preferred unit of measurement (Degrees or Radians). Enter the value of your angle into the text box. The calculator will instantly process the trig function and output the exact decimal ratio.
