What Is Arctan Equal To As we want arctan to be a function we have to choose a range of output values When you use the arctan to get the polar angle there is an uncertainty of pi because tan x pi tan x You have to use the real and imaginary parts to decide the multiple of pi to add to the arctan output to get the proper polar angle you want
begingroup I suppose your confussion stems from the fact that some pretty well known scientific calculators e g at least some of the Casio ones denote by sin 1 cos 1 tan 1 the inverse trigonometric functions a very poor sloppy choice by those Casio guys and since these calculators are very widely used by high school students and these Why arctan x not equal to frac arcsin x arccos x Is there a counter example that I can use to

On the opposite tan 1 x might as well denote the functional inverse arctan x or the multiplicative inverse cot x because the two functions are frequently used I guess that the first interpretation is more frequent but without guarantee Stack Exchange Network Stack Exchange network consists of 183 Q A communities including Stack Overflow the largest most trusted online community for developers to learn share their knowledge and build their careers
