Introduction to Trigonometry Class 10 Important Questions

Trigonometry is the study of relationships between the sides and angles of a triangle. The ratio of the sides of a right triangle with respect to its acute angle is called trigonometric ratio of the angle. Identities involving trigonometric ratios are called trigonometric identities. The reciprocals of the ratios sin A, cos A and tan A are cosec A, sec A, and cot A respectively. The symbol sin A is used as an abbreviation for ‘the sine of the angle A’. sin A is not the product of ‘sin’ and A. ‘sin’ separated from A has no meaning.
