The arctangent function is the inverse function of y = tan(x).arctan(y) = tan-1(y) = x+ kπFor everyk = {...,-2,-1,0,1,2,...}For example, If the tangent of 45° is 1:tan(45°) = 1Then the arctangent of 1 is 45°:...
You can find the tan inverse of 1 without any calculations: Sketch aright triangleand pick one of the acute angles. Recall that the tan is theratioof the opposite to adjacent side. The tan is equal to 1 when theopposite and adjacent sides have the same length! That is, your triangle ...
Below is aninverse tangent calculator(orarctan calculator), which calculates an angle from the ratio from thetangent function. Enter a result and choose to return radians or degrees, then compute the angle. Inverse Tangent Calculator Using the Arctangent Calculator To use the tool to find the a...
Arctan calculator Arctangent definition The arctangent of x is defined as the inversetangentfunction of x when x is real (x∈ℝ). When the tangent of y is equal to x: tany=x Then the arctangent of x is equal to the inverse tangent function of x, which is equal to y: ...
tan(α) =1/2 Tangent Graph If you graph the tangent function for every possible angle, it forms multiple increasing curves with an asymptote at π/2 and repeating every π radians, or 180°. See values in the table below. Tangent Table ...
y=tan(x)y=tan(x) Then we define the inverse tangent function as: x=tan−1(y)x=tan−1(y) The tangent is a periodic function, which repeats in the range (−π/2,π/2)(−π/2,π/2) with values between −∞−∞ and ∞∞. In the image below, you can see ...
