Tangent of an angle is a trigonometric function generally denoted as ‘tan(θ)’, where ‘θ’ is the angle made by a line from the horizontal axis. ‘Arc tan’ is the inverse of this trigonometric function and Arc tan calculator is the online tool which can give the angle equal to the tangent of a given number.

Example 1: Find the arc tan of the number ‘1’ in the interval of [0,π/2]

To find the ‘Arc tan’, which in reality is the inverse of the trigonometric function‘tan(θ)’, we can work backwards to get the our answer!

If tan(θ) = a (where ‘a’ is a random number,)

then θ = arc tan(a)

Using the similar conversion, the given question says,

arc tan(1) = θ

And we know from the graph of ‘tanθ’, that tan(π/4) = 1

tan(π4) = 1 è π/4 = arc tan(1)

Hence the angle is π/4.

Example 2: Find the arc tan of the number ‘0’ in the interval [-π/2, π/2].

To find the ‘Arc tan’, which in reality is the inverse of the trigonometric function‘tan(θ)’, we can work backwards to get the our answer!

If tan(θ) = a (where ‘a’ is a random number,)

then θ = arc tan(a)

Using the similar conversion, the given question says,

arc tan(0) = θ

And we know from the graph of ‘tanθ’, thattan(0) = 0

tan(0) = 0è0 = arc tan(0)

Hence the angle is ‘0’.
