  # ML Aggarwal Solutions for Class 10 Maths Chapter 18 Trigonometric Identities

In Mathematics, trigonometry is one of the most important and prominent topics to learn. Trigonometry is basically the study of triangles. The terms ‘Trigon’ means triangle and ‘metry’ means measurement. Trigonometric identities class 10 consists of trigonometry ratios such as sine, cosine and tangent in its equations. Even, trigonometry identities class 10 formula are based on these ratios. These identities are used to solve various trigonometry problems.
Trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables, where both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles. There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant and cotangent. These are referred to as ratios since they can be expressed in terms of sides of a right-angled triangle for a specific angle θ
Trig identities are trigonometry equations that are always true, and they're often used to solve trigonometry and geometry problems and understand various mathematical properties. Knowing key trig identities helps you remember and understand critical mathematical principles and solve numerous math problems. The Pythagorean formula is for sines and cosines. It is probably an essential trig identity. Trigonometric identities like finding the sine of an angle will help when determining how much of a certain material is needed to use to construct the building—other examples of different architecture where trigonometric identities are found in cars, desks, and even benches.
