Dear All,
I am having problems with some calculations and I am asking for help or
suggestions.
I am integrating a piecewise defined function. The function is non zero
for some periodic intervals.
When nonzero the function has the form f[x_]:=c * Sqrt[ 1-( (x-a)/b )^2*
UnitStep[1-( (x-a)/b )^2] ]
with a, b, c constants
g[y_]:=Integrate[f[x],{x,0,y}]
I want to plot g[y]
I get a lot of messages that are telling :"Nintegrate failed to
converge to prescribed accuracy"
" Integration converging too slowly" etc.
Does anybody know a fix?
Thanks Vio
