Trigonometry is a branch of mathematics that deals with the study of triangles and the relationships between their sides and angles. One of the fundamental concepts in trigonometry is trigonometric ratios, which are ratios of the sides of a right triangle to its angles. There are six trigonometric ratios – sine, cosine, tangent, cosecant, secant,
