, solve for x, exact answer.


Sorry, there is no algebraic method for
solving equations in which the unknown is

There is no way to find an exact answer,
either.  All we can do is approximate
the solution using iterative methods,
infinite series, or graphical calculator.

The approximate solution by graphical 
calculator is



If you want to know how to do it by
graphical calculator, post again asking
how.
