Hello,
I have a problem with the solution of a linear equation given by sage.
sage: a,b,c,d=var('a,b,c,d') sage: v(t)=at^3+bt^2+ct+d sage: v1(t)=diff(v(t),t) sage: g1=v(0)==0 sage: g2=v(5)==1 sage: g3=v1(5)==0 sage: g4=v(1.5)==0.2 sage: solve([g1,g2,g3,g3],[a,b,c,d]) [[a == r1, b == -10r1 - 1/25, c == 25*r1 + 2/5, d == 0]]
The right solution is a=-62/3675, b=473/3675, c=-16/735, d=0!
What's wrong with my implementation in sage?
Thomas
By the way: How can I realize the typical pre-formatted "sage:... look" in my postings??
