NSolve Command
 NSolve( <Equation> )

Attempts (numerically) to find a solution for the equation for the main variable. For nonpolynomials you should always specify a starting value (see below).
NSolve(x^6  2x + 1 = 0)
yields {x = 0.51, x = 1}.
CAS Syntax
These syntaxes are only available in the CAS View.
 NSolve( <Equation>, <Variable> )

Attempts (numerically) to find a solution of the equation for the given unknown variable. For nonpolynomials you should always specify a starting value (see below).
NSolve(a^4 + 34a^3 = 34, a)
yields {a = 34, a = 0.99}.
 NSolve( <Equation>, <Variable = starting value> )

Finds numerically the list of solutions to the given equation for the given unknown variable with its starting value.

NSolve(cos(x) = x, x = 0)
yields {x = 0.74} 
NSolve(a^4 + 34a^3 = 34, a = 3)
yields {a = 0.99}.
 NSolve( <List of Equations>, <List of Variables> )

Attempts (numerically) to find a solution of the set of equations for the given set of unknown variables.
NSolve({pi / x = cos(x  2y), 2 y  pi = sin(x)}, {x = 3, y = 1.5})
yields {x = 3.14, y = 1.57}.
