1 tan 2 x

Tan 2x is a double-angle trigonometric function that can be represented as tan x, sin x, and cos x.

Trigonometry is a field of mathematics that determines the angles and unknown sides of a triangle using trigonometric ratios. It simplifies the estimation of unknown dimensions of a right-angled triangle by using equations and identities based on this relation. This branch of mathematics is studied using trigonometric ratios such as sine, cosine, tangent, cotangent, secant, and cosecant. A trigonometric ratio is defined as the ratio of the lengths of any two sides of a right triangle. These ratios relate the ratio of sides of a right triangle to the angles in trigonometry. The tangent ratio is calculated by computing the ratio of the length of the opposite side of an angle divided by the length of the adjacent side. It is denoted by the abbreviation tan.

Tan2x is an important trigonometric function. 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. As we know that tan x is the ratio of sine and cosine function, therefore the tan2x identity can also be expressed as the ratio of sin 2x and cos 2x. We will also explore the graph of tan2x and its period along with the concept of tan square x and solve examples for a better understanding. Tan2x is a trigonometric function and has a formula that is used to solve various problems in trigonometry. Tan2x is an important double angle formula, that is, a trigonometry formula where the angle is doubled. It can be expressed in terms of tan x and also as a ratio of sin2x and cos2x. Let us see the tan2x formula:. We can express the tan2x formula in two different forms. It can be expressed in terms of tangent function only and as a combination of the sine function and cosine function. The formula for tan2x identity is given as:. Tan2x formula can be derived using two different methods. First, we will use the angle addition formula for the tangent function to derive the tan2x identity. We will use the following trigonometric formula to prove the formula for tan2x:.

In any given right triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side. Already booked a tutor?

Inverse tan is one of the inverse trigonometric functions and it is written as tan -1 x and is read as "tan inverse x". It is also known as arctan x. We have 6 inverse trigonometric functions that correspond to six trigonometric functions. The inverse tan function is one among them. Here, we will study in detail about the inverse tan function arctan along with its properties, graph, domain, and range. Also, we will learn the formulas, derivative, and integral of tan inverse x along with a few solved examples. The inverse tan is the inverse of the tan function and it is one of the inverse trigonometric functions.
