Solution to equations
Associated with the 7key there are two menus of
Symbolic solution of algebraic equations
Here we describe some of the functions from the Symbolic Solver menu. Activate the menu by using the keystroke combination „Î. With system flag 117 set to CHOOSE boxes, the following menu lists will be available:
Functions ISOL and SOLVE can be used to solve for any unknown in a polynomial equation. Function SOLVEVX solves a polynomial equation where the unknown is the default CAS variable VX (typically set to ‘X’). Finally, function ZEROS provides the zeros, or roots, of a polynomial.
Function ISOL
Function ISOL(Equation, variable) will produce the solution(s) to Equation by isolating variable. For example, with the calculator set to ALG mode, to solve for t in the equation
