What is the Arctan Function?

Arctan is an inverse trigonometric function that is used to determine the angle whose tangent value is given. It is the inverse function of tangent. It is denoted as arctan⁡(x), tan−1(x), or inverse tangent where x is a real number that represents the tangent of the angle.

It is a periodic function whose domain is between (∞,-∞) and range is between (𝜋/2,-𝜋/2). It has many applications in mathematical geometry, physics, and engineering fields.

Formula of Arctan Function:

The formula of the arctan function consists of the adjacent side and opposite side of a triangle which is denoted with a and b respectively and 𝜃 is the angle whose value is evaluated. The formula behind the tan inverse calculator is,

$$ tan(\theta) \;=\; \frac{a}{b} $$

$$ \theta \;=\; arctan (\frac{a}{b}) $$

How to Calculate Arctan Function?

The arctan calculator uses the basic value of the arctan function. For the calculation of the arctangent function (arctan⁡(x)) you need to know whether your given trigonometric function is periodic or not.

As the tangent is the periodic function it has its range between (𝜋/2,-𝜋/2). Here’s a step-by-step guide for finding arctan⁡(x) through the approximation method:

Step 1:

The inverse tan calculator identifies the value of x for which you need to find arctan⁡(x).

Step 2:

Put the value of x into the arctan(x) to get the value of the tangent angle.

Step 3:

You can use the tangent calculator to find the tangent value of arctan x as a solution.

Solved Example of Arctan Function:

Find the arctan value at x = 1/2?

Solution:

Given that x=1/2

$$ x \;=\; tan \theta $$

$$ \theta \;=\; arctan(x) $$
$$ Put\; x \;=\; \frac{1}{2} $$

$$ \theta \;=\; arctan(\frac{1}{2}) $$

$$ \theta \;=\; 0.4636 $$

Frequently Ask Questions

What is the arctan of -1?

The value of arctan⁡(−1) is the angle whose tangent value is -1. As the tangent is a periodic function that means it again reverses back to its position so the angle value may be positive or negative. Therefore,

$$ arctan⁡(−1) \;=\; \frac{−π}{4} $$

$$ arctan⁡(−1) \;=\; −45 $$

What is the arctangent of 21?

The arctangent of 21 is:

$$ =\; arctangent\; 21 ≈ 1.51259 $$

Now convert this into a degree:

$$ =\; \frac{1.51259 \times 180}{π} $$

$$ ≈ 86.82° $$

What is the domain of arctan?

The domain of the arctangent function, denoted as arctan⁡(x) has the domain of the set of all real numbers. This means you can input any real number into the arctangent function and get a valid result.

What is arctan x equal to?

The arctangent function is denoted as tan−1(x) as it represents the angle whose tangent value is x value. Mathematically, if you have an angle θ such that:

$$ tan(θ) \;=\; x $$

$$ θ \;=\; arctan\; (x) $$

What if the arctan denominator is zero?

If the arctangent function denominator becomes zero, then it leads to a special case which typically means you're dealing with a special case in which the tangent function itself becomes an undefined function at specific points.

What is arctan 0 in deg?

The value of arctan⁡(0) in degrees is zero the given value of tangent in x.

$$ So:\; x \;=\; tan\; θ $$

Rewrite the above expression

$$ θ \;=\; arctan\; x $$

$$ As\; x \;=\; 0\; then, $$

$$ θ \;=\; arctan(0) $$

$$ θ \;=\; 0 $$

How to calculate arctan ¾?

To calculate arctan⁡(3/4), you have the given value is 3/4, then angle value is:

$$ θ \;=\; arctan ⁡(\frac{3}{4}) $$

$$ θ \;=\; arctan⁡(0.75)\; as\; \frac{3}{4} \;=\; 0.75 $$
