All trigonometric formulas for jee

Trigonometry is a branch of mathematics that studies the relationship between the sides and angles of a right-angled triangle. It is one of the most important branches in the history of mathematics. Hipparchus, a Greek mathematician, introduced this concept.

In mathematics, trigonometry is one of the most important topics to learn. Trigonometry is the study of triangles, where "Trigon" means triangle and "metry" means measurement. A list of trigonometric formulas was formulated for the right triangle. All trigonometric formulas are based on identities and ratios. The relationship between a triangle's side and angle lengths is formulated using trigonometric concepts. A list of formulas based on trigonometry will help students solve trigonometry problems quickly.

Trigonometric equations are those which involve trigonometric ratios. Finding the solution to a trigonometric equation requires finding the value of the angles satisfying the equation. If the interval of the solution is provided, the value of angles has to be found. If the interval is not given, the general solution has to be found. The mathematical expressions which include the ratios of the sides of a right-angled triangle can be called trigonometric expressions. An algebraic equation which involves trigonometric ratios and expressions is known as a trigonometric equation. It comprises all the solutions of trigonometric equations. Example 3: If the two angles on the base of a triangle are Example 4: If the angles of a triangle be in the ratio 1 : 2 : 7, then what is the ratio of its greatest side to the least side? Example 6: Find the principal solutions of the below trigonometric equations. The following identities need to be recalled to find the principal values:. Example 7: Find the general solutions of the following. In a trigonometric equation, the variables used are trigonometric functions. In algebraic equations, alphabets like x, y, etc. Put your understanding of this concept to test by answering a few MCQs.

Hey there! We receieved your request. What is an Identity? As the name suggests, an equation is said to be an identity if it holds good in every case. A trigonometric equation is hence an identity if it is true for all values of the angle or angles involved. A given identity may be established by reducing either side to the other one, or reducing each side to the same expression, or any other convenient modification.

Hey there! We receieved your request. The trigonometric ratios are the ratios between the two sides of a right-angled triangle with respect to an angle and hence they are real numbers. Various trigonometry formulas related to the basic trigonometric ratios which must be remembered include:. Trigonometric Function. Given below is the trigonometry table of the basic ratios for some frequently used angles. These formulas must be memorized as they are used in almost all questions:. Some other formulas of trigonometry which are useful in solving questions:.

Hey there! We receieved your request. As the name implies, trigonometric identities consist of various formulae which are equalities that involve trigonometric functions and are true for every value of the occurring variable. Geometrically, these identities involve functions of one or more angles. They are particularly useful for simplification of trigonometric problems. The topic of Trigonometric identities is also important as it fetches some direct questions in JEE on the basis of formulae.
