NSolutions Command

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}.

Note: It is optional to give the starting point like a=3.

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.
