Hi Mathematica community,
I have this system of equations:
Reduce[{i >= iP, v + a*t/(1 - d) == vP + a*tP/(1 - d),
t/d^(x/a) == tP/d^(xP/a), a*i + 1*x == a*iP + 1*xP,
t/d^(i/-1) == tP/d^(iP/-1),
z - c*x*(x - a)/(2*a) == zP - c*xP*(xP - a)/(2*a),iP==0},
{iP,tP,vP,xP,zP},Backsubstitution->True]
But mathematica still in running until I abort.Could you tell me what
is the problem?
Thank you.
