This command works in CAS View only.
- CSolutions[ <Equation> ]
- Solves a given equation for the variable x and returns a list of all solutions, allowing for complex solutions.
- Example:
CSolutions[x^2 = -1]
gives {ί, -ί}, the complex solutions of x2 = -1.
- CSolutions[ <Equation>, <Variable> ]
- Solves an equation for a given unknown variable and returns a list of all solutions, allowing for complex solutions.
- Example:
CSolutions[a^2 = -1, a]
gives {ί, -ί}, the complex solutions of a2 = -1.
- CSolutions[ <List of Equations>, <List of Variables> ]
- Solves a set of equations for a given set of unknown variables and returns a list of all solutions, allowing for complex solutions.
- Example:
CSolutions[{y^2 = x- 1, x = 2 * y - 1}, {x, y}]
gives \begin{pmatrix}1 + 2 ί&1 + ί\\1 - 2 ί&1 - ί\end{pmatrix}, the complex solutions of y2 = x - 1 and x = 2 * y - 1.
Note:
- The complex ί is obtained by pressing ALT + i.
