WebWriting a complex number in polar form involves the following conversion formulas: x = rcosθ y = rsinθ r = √x2 + y2 Making a direct substitution, we have z = x + yi z = (rcosθ) + i(rsinθ) z = r(cosθ + isinθ) where r is the modulus and θ is the argument. We often use the abbreviation r cisθ to represent r(cosθ + isinθ). http://scipp.ucsc.edu/~haber/archives/physics116A10/arc_10.pdf

WebDec 26, 2024 · I am assuming you have the requisite knowledge of radians and the unit circle in this answer. Your question just seems to be a question on why $\arctan({-\sqrt{3}}) = -\frac{\pi}{3}$.The definition of $\arctan$ is just the inverse of the tangent function. If you know how to take the tangent of an angle, then you know the arctangent. WebMar 27, 2024 · A Computer Science portal for geeks.
