In mathematics, the inverse trigonometric functions (occasionally also called antitrigonometric, [1] cyclometric, [2] or arcus functions [3]) are the inverse functions of the trigonometric functions, under suitably restricted domains.

Arctan. Arctangent, written as arctan or tan-1 (not to be confused with ) is the inverse tangent function. Arctan graph. The graph of y = arctan(x) is shown below. The domain of y = arctan(x) is all x values and its range is . One of the properties of inverse functions is that if a point (a, b) is on the graph of f, the point (b, a) is on the ...

The basic formula for arctan is given as θ = arctan(Perpendicular / Base). The derivative of arctan is d/dx(tan -1 x) = 1/(1+x 2 ). The integral of arctan is ∫tan -1 x dx = x tan -1 x - ½ ln |1+x 2 | + C

Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.

The arctangent function is the inverse function of y = tan(x). arctan(y) = tan-1 (y) = x+ kπ. For every. k = {...,-2,-1,0,1,2,...} For example, If the tangent of 45° is 1: tan(45°) = 1. Then the arctangent of 1 is 45°: arctan(1) = tan-1 (1) = 45° Arctangent table

Arctan definition. The arctangent of x is defined as the inverse tangent function of x when x is real (x ∈ℝ). When the tangent of y is equal to x: tan y = x. Then the arctangent of x is equal to the inverse tangent function of x, which is equal to y: arctan x= tan-1 x = y. Example. arctan 1 = tan-1 1 = π/4 rad = 45° Graph of arctan ...

Use this arctan calculator to quickly find the inverse tangent. Whether you're looking for a simple answer to the question "what is an arctan?" or are curious about the integral or derivative of arctan, you've come to the right place.

The arctan function is the inverse of the tangent function. It returns the angle whose tangent is a given number.

Feb 18, 2024 · Arctan is a reference to the inverse function of the tangent. Symbolically, arctan is represented by tan-1x in trigonometric equations. As discussed above, the basic formula for the arctan is given by, arctan (Perpendicular/Base) = θ, where θ is the angle between the hypotenuse and the base of a right-angled triangle.

arctan(1) = π/4 radians = 45° Key Notes: The range of arctan(x) is from −π/2 to π/2 radians (or −90° to 90°). It accepts any real number as input (unlike arccos/arcsin). It’s useful in right triangle trigonometry and calculus.
