How can I interpret$~\tan^{}\left(x\right),\ln\left(\tan^{}\left(x\right)\right)~$with$~0<x<\pi~$? I think banned-inputs exist in this range

Max area: Quadrilateral with fixed perimeter and interior angle

Does $\int_{0}^{\infty} \sin^x(x) dx$ converge?

How do we know Taylor's Series works with complex numbers?

Can a ratio of sinusoidal functions with the same frequency always be written as a tangent function?

$\arcsin(\sin x)$ explanation?

What is the value of $\sin 1 ^\circ \sin3^\circ\sin5^\circ \sin 7^\circ \sin 9^\circ \cdots \sin 179^\circ $?

An Unexpected Circle...

Does the series $\sum \sin^{(n)}(1)$ converge, where $\sin^{(n)}$ denotes the $n$-fold composition of $\sin$?

How fast are you moving on the earth at a given latitude?

Prove that if $x$ is a non-zero rational number, then $\tan(x)$ is not a rational number and use this to prove that $\pi$ is not a rational number.

Angles satisfying $(\cos\theta,\sin\theta)=(\frac{\sqrt a }{\sqrt{a+b}},\frac{\sqrt b}{\sqrt{a+b}})$ for integer $a$, $b$

$\arctan$ of a square root as a rational multiple of $\pi$

When does this equation $\cos(\alpha + \beta) = \cos(\alpha) + \cos(\beta)$ hold?

Evaluate $\int_{0}^{\frac{\pi}{2}}\frac{dx}{\left(\sqrt{\sin x}+\sqrt{\cos x}\right)^2}$
