Coterminal Angle Calculator
This calculator helps you find the coterminal angle in degrees for any given angle expressed in radians. Coterminal angles are angles that share the same terminal side when drawn in standard position. Understanding coterminal angles is essential in trigonometry, particularly when working with periodic functions.
To use this calculator, simply input your angle in radians, and it will return the equivalent coterminal angle in degrees. This tool is useful for students, engineers, and anyone needing to convert angles for various applications in mathematics and physics.
Formula
The formula used in this calculator is straightforward: the coterminal angle in degrees is calculated by multiplying the angle in radians by \( \frac{180}{\pi} \). Here, "angle" is the input angle in radians, and "angleAsDegrees" is the output coterminal angle in degrees.
How to use
- Enter the angle in radians into the input field.
- Click the "Calculate" button.
- View the coterminal angle in degrees displayed on the screen.
FAQ
What is a coterminal angle?
Coterminal angles are angles that differ by a multiple of 360 degrees (or \( 2\pi \) radians) and thus share the same terminal side when drawn in standard position.
How do I convert radians to degrees?
To convert radians to degrees, multiply the radian measure by \( \frac{180}{\pi} \).
Can this calculator handle negative angles?
Yes, this calculator can handle both positive and negative angles, providing the correct coterminal angle in degrees for any input.
