![]() tan^2x = sin^2x / cos^2x ⇒ tan 2x = sin 2x/cos 2x.We use the tan^2x formula to solve complex integration and differentiation problems and simplify trigonometric expressions. Tan square x is the square of the trigonometric function tan x and is mathematically written as tan^2x. Tan2x formula in terms of sin x and cos x is given by tan2x = 2 sin x cos x /(cos 2x - sin 2x) What is Tan Square x? What is the Formula of Tan2x in Terms of Cos x and Sin x? The integral of tan2x is given by (-1/2) ln |cos 2x| + C or (1/2) ln |sec 2x| + C. The derivative of tan2x can be calculated using different methods such as the chain rule and quotient rule. The range of tan2x is all real numbers, that is, R. The domain of tan2x consists of all real numbers except those where tan2x is not defined. Tan2x formula can be expressed in different ways such as: The commonly used formula for tan2x is tan2x = 2tan x / (1 − tan 2x). Tan2x formula is one of the very commonly used double angle trigonometric formulas and can be expressed in terms of different trigonometric functions such as tan x, cos x, and sin x. Hence we have derived the tan2x formula by expressing it as a ratio of sin 2x and cos 2x.įAQs on Tan2x Formula What is Tan2x in Trigonometry? We will use the following trigonometric formulas:ĭivide the numerator and denominator of 2 sin x cos x/(1 - 2 sin 2x) by cos 2x Now, we will derive the tan2x formula by expressing tan as a ratio of sin and cos. Hence, we have derived the tan2x formula using the angle sum formula of the tangent function. tan (a + b) = (tan a + tan b)/(1 - tan a tan b).We will use the following trigonometric formula to prove the formula for tan2x: Note that we can write the double angle 2x as 2x = x + x. ![]() First, we will use the angle addition formula for the tangent function to derive the tan2x identity. Tan2x formula can be derived using two different methods. ![]()
