If someone wants to see how to solve equation $\displaystyle x \tan(x) =1$ Check this page https://www.hindawi.com/journals/ijem/2015/523043/ The way it works is by finding a polynomial with same roots as the transcendental equation. Last edited by skipjack; January 16th, 2019 at 07:04 AM.

It contains Fourier series, CauchySchwarz integral, complex variables, matrix, differentiation, number of roots, etc. So I was not sure where to post it. Last edited by skipjack; January 16th, 2019 at 07:06 AM.
