The following is a calculator to find out either the arctan value of a number or tangent value of an angle. Using special angles to find arctan.
The value of arctan approaches π/2 as x approaches infinity. Also, we know that tan (π/2) = ∞. So, the limit of arctan is equal to π/2 as x tends to infinity.
The arctan function is the inverse of the tangent function. It returns the angle whose tangent is a given number. Try this Drag any vertex of the triangle and see how the angle C is calculated using the arctan () function.
Arctan of infinity. What is the arctangent of infinity and minus infinity? arctan(∞) = ? The arctangent is the inverse tangent function. The limit of arctangent of x when x is approaching infinity is equal to pi/2 radians or 90 degrees: The limit of arctangent of x when x is approaching minus infinity is equal to -pi/2 radians or -90 degrees:
The principal value of the inverse tangent is implemented as ArcTan [z] in the Wolfram Language. In the GNU C library, it is implemented as atan (double x). The inverse tangent is a multivalued function and hence requires a branch cut in the complex plane, which the Wolfram Language 's convention places at and .
