NSolve Command
From GeoGebra Manual
- NSolve[ <Equation> ]
- Finds a numeric solution for a given equation for the main variable.
- Example:
NSolve[cos(x) = x]
yields {x = 0.7390851332151606}.
- NSolve[ <Equation>, <Variable> ]
- Finds a numeric solution to an equation for the given unknown variable.
- Example:
NSolve[a^4 + 34a^3 = 34, a]
yields {a = -34.00086498588374, a = 0.9904738885574178}.
- Note: It is optional to give the starting point like a=3.
- NSolve[ <List of Equations>, <List of Variables> ]
- Finds a numeric solution to a set of equations for the given set of unknown 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}.
Note:
- The number of decimals depends on the choosen in global rounding.
- π is obtaind by pressing Alt + p.
