Trigonometry identities class 11

Mathematics is divided into various branches that have their importance. Among them, Trigonometry is one such vital branch of mathematics that studies the relationship between the angles of a right-angled triangle and its side lengths. Trigonometry emerged in the 3rd century BC, when the Greek mathematicians like Archimedes and Euclid studied the properties of the chord, calculated and geometrically presented them to prove theorems that are identical to modern trigonometric formulas. Hipparchus of Nicaea is considered the father of Trigonometry and has been given the credit for compiling the first trigonometric table. Basically, Trigonometry is defined with six main ratios, namely Sine(sin), Cosine(cos), Tangent(tan), Cosecant(cosec), Secant(sec) and Cotangent(cot). (image will be uploaded soon) In the above-given picture of a right-angled triangle, the longest side is known as hypotenuse. The other two opposite sides of the hypotenuse are called adjacent and opposite. The angle between the adjacent and opposite is 90°. The important trigonometric formula for class 11 are as follows: 1. sin A = opposite/ hypotenuse = a/ c 2. cos A = adjacent/ hypotenuse = b/ c 3. tan A = opposite/ adjacent = a/ b = ( a/c)/( b/c) = sin A/ cos A 4. cosec A = 1/ sin A = hypotenuse/ opposite = c/ a 5. sec A = 1/ cos A = hypotenuse/ adjacent = c/ b 6. cot A = 1/ tan A = adjacent/ opposite = cos A/ sin A = b/ a Below given is the list of special trigonometry formulas for class 11. They are: 1. P...

Interactive Exercises • • 6.2 Trigonometric identities (EMBHH) An identity is a mathematical statement that equates one quantity with another. Trigonometric identities allow us to simplify a given expression so that it contains sine and cosine ratios only. This enables us to solve equations and also to prove other identities. Quotient identity Quotient identity • Complete the table without using a calculator, leaving your answer in surd form where applicable: \(\theta = \text\). temp text Worked example 5: Trigonometric identities Write the expression in terms of sine and cosine only We use the square and quotient identities to write the given expression in terms of sine and cosine and then simplify as far as possible. • \begin Worked example 6: Trigonometric identities Simplify the left-hand side This is not an equation that needs to be solved. We are required to show that one side of the equation is equal to the other. We can choose either of the two sides to simplify. \begin\) since the numerator and the denominator are the same. \begin\). \begin
