Atan vs arctan
WebMay 26, 2024 · 3 Answers. Sorted by: 1. That is because, when you want to determine the argument of a complex number z = x + i y, really you have to solve, not a single trigonometric equation, but a system of trigonometric equations: { cos θ = x x 2 + y 2 sin θ = y x 2 + y 2. This system implies the equation tan θ = y x, but the converse is not true, and ... WebThis article describes the formula syntax and usage of the ATAN function in Microsoft Excel. Description Returns the arctangent, or inverse tangent, of a number. The arctangent is the angle whose tangent is number. The returned angle is given in radians in the range -pi/2 to pi/2. Syntax ATAN (number)

WebThere's an angle in QII, namely 135 degrees, whose tangent is -1, and there's an angle in QIV, namely 315 degrees (or -45 degrees, if you prefer) whose tangent is -1. In order for arctan to be a function, arctan(-1) must have just one value, and the same has to be true for arctan(x), no matter what real number x stands for.
WebMay 4, 2015 · It is denoted in many ways, including atan θ, arctan θ, and tan − 1 θ. Note that I've only defined tan θ for a limited collection of θ: to get other values, you can use the identities tan ( − θ) = − tan ( θ) and tan ( π + θ) = tan θ. So for instance, if you knew that tan ( π / 4) = 1, then you would also know that.
