I have a sort of unexpected problem with mathematica.
i tried the following:
Plot[NIntegrate[((Sin[t x])^2),{x,0,Pi}],{t,0,10}]
this should give some sort of plot which is always positive,
since the integrand is the square of a real. however,
this function has some sort of problem for t<2 on this plot.
plotting from {t,0,1.7} yields a more convincing plot, but
{t,0,1.8} gives the same sort of error as {t,0,10}.
Is something wrong with my understanding of this function?
the command plots the integral against the parameter t, right?
any help would be appreciated. thanks.
