Pardon me if it sounds like another thread asking how to use the Casio fx991-es calculator again. I searched for some time but couldn't find something that does what I am trying to do.
I know the fx991-es can solve simultaneous equations but it seems that I can only enter equations that are well separated like 2x+4y=8.
But usually simultaneous don't come in this form, especially when doing problems involving like the Lagrange multiplier which would give a hell mess of simultaneous equations. The simultaneous equations usually come in like: yz=x, 2y+z/x=5, or even sin(x)+cos(y)=0, etc...
Can the calculator to solve a set of simultaneous equations that has such equations?
