NSolutions Command

CAS Syntax

NSolutions[ <Equation> ]

Finds a numeric solution for the given equation for the main variable.

Example:
NSolutions[cos(x) = x] yields {0.74} or {0.739085133215165} (the number of decimals depends on the choosen in global rounding)

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}

Note: 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.
