operations, and can perform high-precision solutions. It implements the function of an equation solver, simplifying the cumbersome manual calculation process.
- The equation text is retrieved and analyzed by a lexical analyzer to construct a
binary tree
, which enables the analysis and processing of the text expression. - Subsequently, the type and solution method of the equation are determined based on the text expression.
- If it is a
single-variable
equation, the equation's degree is determined by the analytical result of the equation.- If it is a
quadratic
orcubic
equation, the solution is obtained using the formula method. - If it is a
linear
equation or ahigher-degree
equation, the Newton-Raphson iteration method is used to find the approximate root.
- If it is a
- If it is a
multi-variable
equation, the augmented matrix is extracted.- If the equation has a
unique solution
, Cramer's rule is applied to solve it. - If there are
multiple solutions
orno solution
, elementary row operations are used to find the particular solution.
