Web28 jun. 2024 · 2 Answers. Niven's Theorem: If x / π (in radians) and sin x are both rational, then the sine takes values 0, ± 1 / 2, and ± 1. Obviously, angle in radians is a rational multiple of π iff angle in degrees is rational. Let us take the Pythagorean theorem a 2 + b 2 = c 2 and divide both sides by c 2 to get a 2 c 2 + b 2 c 2 = 1. Web25 apr. 2024 · There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). Why there are only 6 trigonometric functions? There are only 6 trigonometric ratios because only 6 ratios can define ratios of all sides.
