Precision plots - How do I do those?
I have a function which varies so slowly, that in the range I'm interested only the 17th decimal changes.
The sws is this:
sage: mp = 139570180. sage: mm = 105658371.5 sage: mn = 1. sage: dmp = 350. sage: dmm = 3.8 sage: dmn = 0.1 sage: l(a,b,c) = a^2 + b^2 + c^2 - 2*( a*b + b*c + c*a ) sage: f(x) = sqrt(l(mp^2, mm^2, x^2))/(2*mp) sage: R=RealField(100) sage: g = fast_callable(f, vars=[x], domain=R) sage: plot( g, (x,0,2))
but I got the following plot, which is unsatisfactory in several ways!
How could I possible improve it? (ticks on vertical axis, a "continuous" line, ...)
