Hi, The following bit of code correctly computes the triple integral (64\pi/3) for the volume of an ellipse given by 4x^2 + 4y^2 + z^2=16: assume(0 < 16 - 4*x**2 - 4*y**2 < 16) i1 = integral(1,0,sqrt(16 - 4*x**2 - 4*y**2)) show(i1) assume(0 < 4 - x**2 < 4) i2 = integral(i1,y,0,sqrt(4 - x**2)) sho

Hi, First of all I am using a coupled 2sd ODE. First step was to declare variables: a,l,x,y,u,v,xdot,ydot,udot,vdot = var('a,l,x,y,u,v,xdot,ydot,udot,vdot', domain = RR) Second step turn the two 2sd ODE into four 1st ODE. xdot = u; ydot = v; udot = -(1-a)*((x-a)/(sqrt((x-a)^2 + y^2))^3)
