fsolve or nSolve with the option brent_solver

The Brent method interpolates of f at three points, finds the intersection of the interpolation with the x axis, computes the sign of f at this point and chooses the interval where the sign changes. It is generically faster than bisection.
Input :
fsolve((cos(x))=x,x,-1..1,brent_solver)
Output :
[0.73908513321 5,0.739085133215]
