Tangent calculator
What is a Tangent Calculator?
A Tangent Calculator is a tool that calculates the tangent (tan) of a given angle. In trigonometry, the tangent of an angle in a right triangle is the ratio of the opposite side to the adjacent side:

For angles measured in radians or degrees, the calculator quickly finds the tangent value.
Why use a Tangent Calculator?
- Saves time: Quickly computes tangent without manual calculations.
- Accuracy: Reduces risk of calculation errors.
- Solving triangles: Finds missing sides or angles in right-angled triangles.
- Real-world applications: Used in physics, engineering, navigation, and architecture.
How does a Tangent Calculator work?
- Input: You enter an angle (in degrees or radians).
- Calculation: It applies the tangent function:
- Output: The resulting tangent value.
Example:
- For θ = 45°, tan(45 ∘) = 1
When to use a Tangent Calculator?
- Solving triangles: Finding missing side lengths when one side and one angle are known.
- Physics: Calculating slopes, angles of elevation, or projectile motion.
- Engineering: Determining forces, inclines, and angles in design.
- Construction: Measuring pitch of roofs or angles for structures.
