simplifying equation - Mensajes
#1 Publicado: 27/1/2019 14:38:08
Hello, maybe someone could help, then I solve the equation with symbols it doesn't solve (I've attached the file), when I make simplification for my self it solve:
example p:=solve(b*x*x/2+a*As2*(x-d2)=a*As1*(d-x),x) it says no real roots
then I simplified by mysef
p:=solve(0.125x^2+0.0491x-0.01998=0, x) it give answer?
best regards,
Paulius

Hello, maybe someone could help
1. recast the functions unitless
2. plot
3. solve implicit in this case.

Hi. You need to handle units in the SMath solve function. Here it's a way.
Best regards.

Solve() from the Maxima plugin can handle units directly (symbolic solver)
