About LinkBacksQuestion about limit.
Show that the equation cosx=2x has a migue solution x∈r.
if you know anything this question I want to hear your idea.
I can't understood migue solution.Have you any idea about this solution I'm waiting.
Thank you.

I think he means a unique solution.
The derivative ofis
, which is always positive, so the function is increasing. Also,
for large negative values of x and
for large positive values of x. So there is exactly one
where it is zero, and that is a unique solution to
