Trigonometric Ratios
... Special Triangles To find the values of the trigonometric ratios for other angles, we use a calculator. Mathematical methods (called numerical methods) used in finding the trigonometric ratios are programmed directly into scientific calculators. Calculators give the values of sine, cosine, and tang ...
