This command works in CAS View only.
- NSolve[ <Equation> ]
- Finds a numeric solution for a given equation (or a set of equations) for the variable x.
- Example:
NSolve[sin(x) = x]gives you {x = 0}.
- NSolve[ <Equation>, <Variable> ]
- Finds a numeric solution to an equation (or a set of equations) for a given unknown variable (or set of variables).
- Example:
NSolve[a^4 + 34a^3 - 34, a]gives you {a = 0.99}.
- NSolve[ <Equation>, <Variable> ]
- Finds a numeric solution to an equation (or a set of equations) for a given unknown variable (or set of variables).
- Example:
NSolve[{π / x = cos(x - 2y), 2 y - π = sin(x)}, {x=3, y=1.5}]yields {x = 3.141592651686591, y = 1.570796327746508}.
Note:
- It is optional to give the starting point like {x=3, y=1.5}.
- See also Solve Command.
