(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

for the equation tanx=x in (npi-pi/2,npi+pi/2)for n is integers. show that it has precisely one solution.

without ploting the graph. use analysis

3. The attempt at a solution

i have try to assume two solutions then apply the rolles theorem but i cannot do in this way since assume two roots c1 and c2 then exists c s.t. f'(c)=o but f‘(x)=(tanx)^2>=0

can someone give me some helps
