nsolve vs fsolve ? - dg1969 - 11-30-2014 09:13 PM


What is exactly the difference between these two commands ?

What is the syntax to solve system of non linear equations with nsolve command ?


RE: nsolve vs fsolve ? - DrD - 11-30-2014 09:59 PM

nSolve({list of equations), {list of variables}) ---> {list of solutions}

nSolve({(x+2*y) = 10,(y-x) = 2},{x,y}) ---> {2,4}

User Guide distinction:
nSolve((Expr, Var=Guess)
fsolve(Expr, Var, [guess or interval], [Method])

CAS commands:
nSolve() spelling.
fsolve(), spelling (all lower case).
