Free trigonometry calculator - calculate trignometric equations, prove identities and evaluate functions step-by-step.
The sine of theta (sin θ) is the hypotenuse's vertical projection (green line); and The cosine of theta ( cos θ ) is the hypotenuse's horizontal projection (blue line). We can rotate the radial line through the four quadrants and obtain the values of the trig functions from 0 to 360 degrees , as in the diagram below:
