Question about the use of the CAS solve function in a program

[Gene222]

Regarding the variables used in solve, if the known variables and solve variable are equal to zero and the equation is exact in form, solve will try to find all solutions - symbolically. For example, when running your program with x=0, y=0 and not providing a guess for n (thus n=0), solve will return -sqrt(2), 0, sqrt(2) in brackets. This appears to be another way to symbolically solve an equation in a program.
