1. The inverse trigonometric function that returns the angle whose tangent is a given number; often written as arctan or tan⁻¹.
Usage: mathematics; Also called inverse tangent or anti-tangent

Examples

• The arctangent of 1 is π/4 radians, or 45 degrees.
• To find the angle, we need to calculate the arctangent of the opposite side divided by the adjacent side.
• The arctangent function is commonly used in engineering to convert slope measurements into angles.
• In programming, the arctangent is often accessed through the atan() function.
• The range of the arctangent function is between -π/2 and π/2.
