solve/radical

expressions involving radicals of unknowns

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

solve(eqns, vars)

Parameters

eqns

-

equations (as for solve), but with radicals

vars

-

variables (as for solve)

Description

• 

The solve function will solve equations with radicals by using new auxiliary variables and adding new equations.

• 

In some cases the resulting problem will be a system of equations, but in many simple cases radical equations will be handled with transformations and post-processing. For example, the equation x2+x+1=3 is transformed into z42z2+z=2 using the substitution x=z21.
