Trig Function Calculator

Your details

Forward mode: enter an angle and get all six function values. Inverse mode: enter a function value and get the angle.
Choose whether your angle is measured in degrees (0-360), radians (0-2π), or gradians (0-400).
The angle whose trigonometric functions you want to calculate.

All six trig functions at 45°.

  • Pythagorean identity check: sin² + cos² = 1.000000 (should be 1.000000).
  • tan = sin/cos = 0.7071 / 0.7071 = 1.0000.
  • This angle falls in Quadrant I (both sin and cos are positive).

Next stepSwitch to Inverse mode to reverse the calculation - enter any of these values and recover the angle.
