I've been trying to plot the function f:=x->(e^(-a*x^2)-b*x*ln(1+x^2))/(2+x^2+c*sin(Pi*x)); with values a,b,c which have been assigned on maple. when i try to plot the function using: plot(f(x),x=-4..4); I get the error: Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct Error, empty plot I have tried all ways i can possibly think and cannot get it to plot the graph. Can anyone help?
