👉 The term "arctan" is a mathematical function that represents the inverse tangent of a given angle. It is also known as "arc tangent." The arctangent function, denoted by atan(x), returns the angle in radians (or degrees) corresponding to an angle x. For example, if we have an angle θ with a value of 30°, then: atan(θ) = π/6 This means that for every full rotation of 30°
