A Learning Aid, Not Certified Advice

SinCosTan’s calculators — the right triangle calculator, the law of sines and cosines calculator, the degrees to radians converter, the sine wave calculator, the inverse trig calculator, and the trig function and identity calculator — are designed to help you learn trigonometry and check your working. They do not constitute professional, engineering, surveying, or academic advice. For graded coursework, examinations, or any real-world application — construction, navigation, engineering, or similar — confirm every result with a full-precision method and, where appropriate, a qualified professional.

Results Are Rounded Estimates

The tools apply standard trigonometric formulas and round their output for readability. That rounding, together with the assumptions of a deliberately simple model, means a displayed value may differ slightly from a full-precision calculation. Always work to full precision when an application requires it.

Why a Result May Look Off

A calculator can return a surprising or blank answer when:

• Units are mismatched: entering degrees where radians are expected (or the reverse) changes the answer entirely.
• Inputs describe an impossible figure: for example, a triangle leg longer than its hypotenuse, or sides that violate the triangle inequality.
• A function is undefined:tangent at 90°, or an arcsine of a value outside [−1, 1], has no real result.
• The ambiguous case applies: a two-sides-and-an-angle (SSA) setup can describe two different triangles.
