What is the Arctangent of Tangent? - Mathematics Stack Exchange
WEBIt only equals $\theta $ if $$-\frac {\pi}{2}<\theta < \frac {\pi}{2} $$ as the range of $\arctan$ is only from $-\frac {\pi}{2} $ to $\frac {\pi}{2} $. If $\theta $ is outside this interval, then you would need to add or subtract $\pi $ from $\theta $ until you get to the angle in this interval that has the same value of $\tan$.
How to prove that limit of arctan (x) as x tends to infinity, is
WEBWhile working on some probability question, I had to evaluate $\lim_{x \to \infty} \arctan(x)$. I knew the answer intuitively as $\pi/2$, yet I cannot figure out how to prove it by elementary means (without resorting to $\epsilon-\delta$ arguments).
trigonometry - Relationship between $\tanh x$ and $\arctan x ...
WEBThe two functions resemble each other on the real line, but they're not the only sigmoidal functions around. . There are functions as simple as $\dfrac{x}{\sqrt{1+x^2}}$ and as complicated as $\dfrac2{\sqrt \pi}\int_0^x e^{-t^2}\mathrm dt$ that also have the s-s
What 's the differece between $\\cot(x)$ and $\\arctan(x)$?
WEB$\begingroup$ 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 …
