Getting inverse tangent and inverse hyperbolic tangent in Julia – atan(), atanh() and atand() Methods

The atan() is an inbuilt function in julia which is used to calculate inverse tangent of the specified value and output is in radians.

Syntax: atan(x)

Parameters:

• x: Specified values.

Returns: It returns the calculated inverse tangent of the specified value and output is in radians.

Example:

# Julia program to illustrate
# the use of atan() method

# Getting inverse tangent of the specified
# values and output is in radians.
println(atan(0))
println(atan(-0.444))
println(atan(0.7774))
println(atan(1))

Output:

0.0
-0.41785313434757676
0.6608077411382699
0.7853981633974483

The atanh() is an inbuilt function in julia which is used to calculate inverse hyperbolic tangent of the specified value.

Syntax: atanh(x)

Parameters:

• x: Specified values.

Returns: It returns the calculated inverse hyperbolic tangent of the specified value.

Example:

# Julia program to illustrate
# the use of atanh() method

# Getting inverse hyperbolic tangent of the
# specified values.
println(atanh(0))
println(atanh(-0.45))
println(atanh(0.5))
println(atanh(-0.896))

Output:

0.0
-0.48470027859405174
0.5493061443340548
-1.4515553918367974

The atand() is an inbuilt function in julia which is used to calculate inverse tangent of the specified value and output is in degrees.

Syntax: atand(x)

Parameters:

• x: Specified values.

Returns: It returns the calculated inverse tangent of the specified value and output is in degrees.

Example:

# Julia program to illustrate
# the use of atand() method

# Getting inverse tangent of the specified
# values and output is in degrees.
println(atand(0))
println(atand(-0.444))
println(atand(0.7774))
println(atand(1))

Output:

0.0
