Free Sin Cos Tan Calculator
Need sine, cosine, or tangent for any angle? Our free Sin Cos Tan Calculator computes all six trig functions โ sin, cos, tan, csc, sec, and cot โ instantly, in degrees or radians, with exact values shown for standard angles like 30ยฐ, 45ยฐ, and 60ยฐ.
Need to go the other way? Switch to inverse mode to find the angle from a sine, cosine, or tangent ratio using arcsin, arccos, or arctan, with results given correctly within each function's principal value range and in both degrees and radians.
Undefined cases (like tan at 90ยฐ) are clearly labeled instead of showing a broken number, and out-of-range inverse inputs are flagged immediately. A small unit-circle diagram shows exactly what's being calculated. No sign-up, no downloads โ just enter a value and get your answer. See the About page or the FAQ for more.
