NSolutions Command
From GeoGebra Manual
This command works in CAS View only.
- NSolutions[ <Equation> ]
- Finds a numeric solution for a given equation for the variable x.
- Example:
NSolutions[cos(x) = x]
yields {0.7390851332151606}.
- NSolutions[ <Equation>, <Variable> ]
- Finds a numeric solution to an equation for a given unknown variable.
- Example:
NSolutions[a^4 + 34a^3 - 34, a]
yields {0.9904738886662206}.
- NSolutions[ <List of Equations>, <List of Variables> ]
- Finds a numeric solution to a set of equations for a given set of unknown variables.
- Example:
NSolutions[{π / x = cos(x - 2y), 2 y - π = sin(x)}, {x=3, y=1.5}]
yields {3.141592651686591, 1.570796327746508}.
- Note: It is optional to give the starting point like {x=3, y=1.5}.
Note:
- π is obtaind by pressing Alt + p.
