This command works in CAS View only.
- CSolve[ <Equation> ]
- Solves a given equation (or a set of equations) for the variable x and returns a list of all solutions, allowing for complex solutions.
- Example:
CSolve[x^2 = 1]
gives {{x = ί}, {x = -ί}}, the solutions of x2 = 1.
- Solve[ <Equation>, <Variable> ]
- Solves an equation (or a set of equations) for a given unknown variable (or set of variables) and returns a list of all solutions, allowing for complex solutions.
- Example:
CSolve[{y^2 = x- 1, x = 2 * y - 1}, {x, y}]
gives {{x = 1 + 2 ί, y = 1 + ί}, {x = 1 - 2 ί, y = 1 - ί}}, the complex solutions of y2 = x and x = 2 * y - 1.
Note:
- The complex ί is obtained by pressing ALT + i. See also Complex Command.
