Hello, Welcome To CBSE Digital Education. Today We Are Going To Discuss A Interesting Topic About trigonometry formula class 10 . CBSE Digital Education provides all important information regarding the trigonometry formula class 10. Trigonometry Formula Class 10 Trigonometry is that branch of mathematics that deals with the measurement of angles and problems applied with angles. Definition of Trigonometry The word trigonometry is derived from the words ‘trigonon’ and ‘metron’ which mean triangle and measure respectively. It is the study of the relationship between the sides and angles of a right triangle. Thus it helps to find the measure of unknown dimensions of a right-angled triangle by using formulas and identities based on this relation. Meaning of trigonometry: Trigonometry = Tri + gono + metry “Tri” means Triangle “gono” means Angles “metry” means Measurement Trigonometric Ratio Formula Class 10 There are six basic ratios in trigonometry that help to establish the relationship between the ratio of the sides of a right triangle with the angle. • SinA = P/H • CosA = B/H • TanA = P/B • CosecA = H/P • SecA = H/B • CotA = B/P Reciprocal Relation of Trigonometric formulas for class 10 1. Cosec A = 1/Sin A 2. Sin A = 1/Cosec A 3. Sec A = 1/Cos A 4. Cos A = 1/Sec A 5. Cot A = 1/Tan A 6.

2 Solved Examples Trigonometry Formula What is Trigonometry? It is the study of the relationships which involve angles, lengths, and heights of triangles. It also relates to the different parts of circles as well as other geometrical figures. Trigonometry has many trigonometric ratios which are very fundamental in mathematics. It has many identities that are very useful for learning and deriving the many equations and formulas in science. There are various fields where these identities of trigonometry and formula of trigonometry are used. Here we may see many useful trigonometric identities and formulas. Trigonometric formulas involve many trigonometric functions. These formulas and identities are true for all possible values of the variables. Trigonometric Ratios are also very basic to provide the relationship between the measurement of the angles and the length of the side of the right-angled triangle. We will consider the right-angled triangle. In these, we have three sides namely – Hypotenuse, the opposite side (Perpendicular) and Adjacent side (Height). The largest side is known as the hypotenuse, the side opposite to the angle is opposite and the side where both hypotenuse and opposite rests is the adjacent side. There are six ratios which are the core of trigonometry. These are, • Sine (sin) • Cosine (cos) • Tangent (tan) • Secant (sec) • Cosecant (csc) • Cotangent (cot) For each angle, there are six functions in trigonometry. Each function is the ratio of the two s...
