Trigonometric Ratios: A Detailed Explanation Trigonometric ratios are the ratios of the lengths of sides in a right-angled triangle. These ratios are fundamental in trigonometry and are used to relate the angles of a triangle to the lengths of its sides. There are six primary trigonometric ratios. sine, cosine, tangent, cosecant, secant, and cotangent. Here’s […]
