Coverrt Tangent Degrees Calculator

Reviewed by Calculator Editorial Team

This Covert Tangent Degrees Calculator helps you find the tangent of an angle in degrees. Tangent is one of the primary trigonometric functions, essential in geometry, physics, and engineering. The calculator provides quick results with an interactive chart to visualize the tangent function.

What is Tangent?

Tangent (tan) is a trigonometric function that relates the angle of a right triangle to the ratio of the opposite side to the adjacent side. In the unit circle, tangent represents the y-coordinate divided by the x-coordinate of a point corresponding to a given angle.

The tangent function is periodic with a period of 180 degrees, meaning tan(θ) = tan(θ + 180°n) for any integer n. It's undefined where cosine is zero (at 90° + 180°n).

Tangent is particularly useful in calculating slopes, angles of elevation, and various physical phenomena involving waves and oscillations.

How to Use This Calculator

  1. Enter the angle in degrees in the input field.
  2. Click "Calculate" to compute the tangent value.
  3. View the result in the result panel below.
  4. Use the interactive chart to visualize the tangent function.

The calculator handles angles beyond 360° by normalizing them to the equivalent angle between 0° and 360°.

Formula

The tangent of an angle θ in degrees is calculated as:

tan(θ) = sin(θ) / cos(θ)

Where sin(θ) is the sine of θ and cos(θ) is the cosine of θ.

For angles outside the standard range, the calculator first normalizes the angle using modulo 360° to ensure accurate results.

Example Calculation

Let's calculate the tangent of 45 degrees:

  1. Enter 45 in the angle input field.
  2. Click "Calculate".
  3. The result will show tan(45°) ≈ 1.

This matches the known trigonometric identity that tan(45°) = 1.

Angle (degrees) Tangent Value
0° 0
30° ≈ 0.577
45° 1
60° ≈ 1.732
90° Undefined

FAQ

What is the difference between tangent and cotangent?

Tangent (tan) is the ratio of the opposite side to the adjacent side in a right triangle, while cotangent (cot) is the reciprocal of tangent (cot = 1/tan).

Why is tangent undefined at 90°?

At 90°, the cosine of the angle is zero, making the tangent function (sin/cos) undefined because division by zero is not allowed in mathematics.

Can I use this calculator for angles greater than 360°?

Yes, the calculator automatically normalizes angles to the equivalent angle between 0° and 360° before calculation.
