This page is about a feature that is supported only in GeoGebra 4.2. |
CAS Syntax
- NSolutions[ <Equation>, <Variable> ]
- Finds numerically the list of solutions to the given equation for the given unknown variable.
- Examples:
NSolutions[cos(x) = x, x= 0]yields {0.74}NSolutions[a^4 + 34a^3 - 34, a]yields the list {-34, 0.99}.
- Note: It is optional to give the starting point like a=3.
- NSolutions[ <Equation>, <Variable = starting value> ]
- Finds numerically the list of solutions to the given equation for the given unknown variable with its starting value.
- Example:
NSolutions[a^4 + 34a^3 - 34, a=3]yields the list {-34, 0.99}.
- NSolutions[ <List of Equations>, <List of Variables> ]
- Finds numerically the list of solutions to the given set of equations for the given set of unknown variables.
- Example:
NSolutions[{π / x = cos(x - 2y), 2 y - π = sin(x)}, {x=3, y=1.5}]yields the list {3.14, 1.57}
 |
It is optional to give the starting point like {x=3, y=1.5}. |
- Note:
- π is obtaind by pressing Alt + p.
- See also Solutions Command and NSolve Command.
