The proper expression for the fixed-point iteration for the $n$th nonzero solution of $x=\tan\;x$ is $x_{k+1}=\arctan(x_k)+n\pi$.

To solve a trigonometric simplify the equation using trigonometric identities. Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to solve for …

I needed to find, using the bisection method, the first positive value that satisfy $x = \tan(x)$. So I went to Scilab, I wrote the bisection method and I got $1.5707903$. But after some reasoning ...

For each integer n, \tan x is a bijection from (\tfrac{2n-1}{2}\pi,\tfrac{2n+1}{2}\pi) to \mathbb{R}. So for each positive integer n, there is exactly one positive solution to x = \tan x ...

In a right-angled triangle, the formula for the tangent function is expressed as the ratio of the perpendicular and base of the triangle. It can also be expressed as the reciprocal of the …
