I have difficulties to solve this equation :

NSolve[(x^3 + Sin[x]*Cos[x]) == 0, x]

I receive the following error message :

This system cannot be solved with the methods available to NSolve

May you help me to solve this equation ?

    $\begingroup$ Are you aware you are trying to find complex-valued solutions? It works fine if you specify it for reals, doing NSolve[..., Reals] instead. $\endgroup$ – kirma Nov 5 '15 at 18:08
