FWIW : sage: var("t") t sage: integrate(abs(exp(i*t).demoivre()-1)^2*i*exp(i*t), (t,0,pi)) -I*pi - 4 HTH,

FWIW, the question Is floor((%i+1)/(2*%pi)) positive, negative or zero? is nonsensical : $\displaystyle{\frac{i+1}{2\pi}

FWIW : sage: var("a") a sage: foo=1/((x-a)^(1/2)*x^(3/4)) sage: foo.integrate((x, 0, oo)) -----------------------------

Therefore, you want to customize your table for a specific output. Which one ?

A couple suggestions : You might put your figures in separate files, then merging them with an external tool such as p

As far as I understand, you're generating LaTeX output. What about \small{T} ? This tutorial might be helpful. More ge

Your code runs in O(n^3), n being your limit. If you need "about a second" for n=100, it wil need "about 1000 seconds" f

EDIT : A previous answer (seriously out of scope...) has been edited out. Nothing direct, as far as I know. Of note :

What is your bloody question ?

Scipy solvers are numerical solvers, using numerical integration to get a solution of (systems of) ordinary differential
