What is a Tangent Calculator?

A tangent calculator is an online or handheld tool that computes the tangent (tan) value of a given angle. The tangent function is a fundamental trigonometric function defined as the ratio of the opposite side to the adjacent side in a right triangle. It is commonly used in mathematics, physics, engineering, and various fields requiring angle calculations.

How to Use a Tangent Calculator?

Using a tangent calculator is simple:

1. Enter the Angle – Input the angle in degrees or radians.
2. Select the Unit – Choose between degrees (°) or radians (rad) if required.
3. Calculate – Press the "Calculate" button to get the tangent value.
4. Interpret the Result – The output shows the tan(θ) value, which can be positive, negative, or undefined at 90° and 270° (where division by zero occurs).
