Enter any angle in degrees or radians and return the main trig ratios plus unit-circle context.
sin / cos / tan

Enter an angle in degrees or radians to calculate the six trig ratios and see the unit-circle context.
Tap an example to prefill the calculator with sample values.
Standard angle
135 degrees in Quadrant II
A standard unit-circle angle that also produces exact values.
Result: The calculator returns exact unit-circle values and the reference angle.
Negative radian input
-5pi/6 approximated in radians
Useful when you need normalization back into the 0 to 360 degree range.
Result: The tool normalizes the angle and still returns the correct quadrant and trig outputs.
