cSolve takes two arguments and solves an equation or a system
of polynomial equations.
- 
solving an equation
 cSolve takes as arguments an equation between two expressions or an 
expression (=0 is omitted), and a variable name (by default x).
 cSolve solves this equation in ℂ even if you are in
real mode.
- solving a system of polynomial equations
 cSolve takes as arguments two vectors : a vector of polynomial equations 
and a vector of variable names.
 cSolve solves this equation system in ℂ even if you are in
real mode.
Input :
cSolve(x^4-1=3)
Output :
[sqrt(2),-(sqrt(2)),(i)*sqrt(2),-((i)*sqrt(2))]
Input :
cSolve([-x^2+y=2,x^2+y],[x,y])
Output :
[[i,1],[-i,1]]
