Double Angle trigonometric Identity
A Double angles identity is written2θ, for example, as sin 2θ, cos 2α, or tan 2x, where 2θ, 2α, and 2x. The angle measures and the assumption is that you mean sin(2θ), cos(2α), or tan(2x). Because tangent is equal to the ratio of sine and cosine . Therefor its identity comes from their double-angle identities. Double angle
Trigonometric equations
Trigonometric equations use both the reference angles and trigonometric identities The general method of solving an equation is to convert it into the form of one ratio only. Hence, we can obtain solutions. Trigonometric Equation
Trigonometric Identity
The trigonometric identity showing that the identity is always true, no matter what value of x or θ is used. Because it has to hold true for all values of x, we cannot simply substitute in a few values of x to “show” that they are equal. We have to use logical steps to show […]

Product to Sum
Product‐Sum and Sum‐Product Identities. The process of converting products into sums can make a difference . Integrate \( \int \! \sin 3x \cos 4x \, \mathrm{d}x.\) This problem may seem tough at first, but after using the product-to-sum trigonometric formula, this integral very quickly changes into a standard form . Converting a sum of trig functions into a product. Write as and then […]
Trigonometric identity
Trig identity is equations that are true for Right Angled Triangles. D1: sin 2A+ cos 2A=1 D2: 1+ tan 2A= sec 2A D3: 1+ cot 2A= csc 2A Hence trigonometric identities are prove by above D1,D2 and D3. Similarly also using reciprocal identity. Trigonometric Identity
Trigonometric ratio-2
The ratios of the sides of a right triangle are called trigonometric ratios. Sine, Cosine and Tangent are main ratio while rest three reciprocal. Hence Sine and Cosine are the trigonometric ratios, whose values are less that 1 for an acute angle. Because they are periodic. www.kutasoftware.com

Multiple angle identity
Multiple angles identity are nothing but the trigonometric identity of multiple angles. Use for Proof of the double-angle and half-angle formulas. Solving Trigonometric Equations and Identities using Double–Angle and Half- Angle Formulas, examples and step by step solutions. Hence double angle formulae for sin 2A, cos 2A and tan 2A use for solving identity. Also to solve […]
