nsolve vs fsolve ? - dg1969 - 11-30-2014 09:13 PM
Hi,
What is exactly the difference between these two commands ?
What is the syntax to solve system of non linear equations with nsolve command ?
Thanks

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