Coterminal Angle Calculator
Calculate coterminal angles quickly and accurately. Enter any angle in degrees to find its coterminal angles.
Understanding Coterminal Angles
Coterminal angles are angles that share the same terminal side and differ by a multiple of 360°. When two angles are coterminal, they look identical when drawn in standard position.
Key Points About Coterminal Angles:
• The formula for finding coterminal angles is: θ ± 360°n, where n is any integer
• All coterminal angles are equivalent in terms of their trigonometric functions
• The smallest positive coterminal angle is always between 0° and 360°
Common Applications:
Coterminal angles are essential in:
- Trigonometry
- Physics (especially circular motion)
- Engineering calculations
- Navigation and direction finding
