WHAT ARE THE SIX FUNDAMENTAL TRIGONOMETRIC RATIOS? Trigonometric formulas are the six basic trigonometric ratios which establish the ratios of the lengths of the sides with each other in a right angled triangle. the three fundamental trigonometric ratios as sin, cos and tan, which their reciprocal trigonometric ratios cosec, sec and cotan are derived trigonometric ratios.
Addition and Subtraction Formulas for Sine and Cosine: In a right triangle with legs a and b and hypotenuse c, and angle alpha opposite side a, the trigonometric functions sine and cosine are defined as sin(alpha) = a/c, cos(alpha) = b/c
