Trigonometric Functions Reference
sin A = opposite / hypotenuse = a / c
csc A = hypotenuse / opposite = c / a
cos A = adjacent / hypotenuse = b / c
sec A = hypotenuse / adjacent = c / b
tan A = opposite / adjacent = a / b
cot A = adjacent / opposite = b / a
What is a Trigonometry Calculator?
A trigonometry calculator helps solve for the unknown sides and angles of a right-angled triangle. By providing any two known values, you can find the remaining properties of the triangle.
Formula
Calculations are based on the Pythagorean theorem (a² + b² = c²) and trigonometric functions like sine (SOH), cosine (CAH), and tangent (TOA).
