How to Find Arctan(Inverse Tangent)?

In mathematics, arctan is a trigonometric function that finds the value of inverse tangent. And it is represented as tan-1(x). The real numbers of this inverse tangent function are (-∞ - +∞).

Arctan

Arctan Formula:

y = tan(x) | x = arctan(y)

where,

arctan(y) = tan-1(y)

y = angle(a).

Inverse Tangent Graph Or Arctan Graph:

The curve forms for the arctan function is (-∞, –π/2) to (∞, π/2).

Arctan Table:

The below table shows the arctan and tangent functions.

     x arctan(x) in degrees arctan(x) in radians
-∞ -90° -π/2
-√3 -60° -π/3
-1 -45° -π/4
-1/√3 -30° -π/6
0 0
1/√3 30° π/6
1 45° π/4
√3 60° π/3
90° π/2

Steps to Calculate Arctan:

Look into the below steps that calculate the inverse tangent easily and quickly. Follow the steps carefully.

  • Write the finding value that was given in the problem.
  • Then, apply the formula and substitute it.
  • After simplifying you will get the value of the inverse tangent.

Example:

Question: Find the value of arctan (1) in radians?

Solution:

Given arctan(1)=?

As we know,

tan(45°)=1, from the table.

Apply the formula,

y = tan(x) | x = arctan(y)

1 = tan(45°)

45° = arctan(1)

Therefore, the arctan(1) = 45° .
