## selectremove positive real part of compl...

Maple

hi, suppose

integers:=[`\$`(-10..10)]; selectremove(`<`,integers,0);

so this separates +ve and -ve. But, if the range of values are complex, how do we separate them based on the +ve and -ve of the real part of the complex number? i.e I want to separate all a +- bi from all -a +- bi.

thanks

## plot sin(pi x)...

Maple

Hi I am trying to plot sin (pi x) but maple says

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

I cant understand this warning, as when i put 3.14 instead of pi it plots a nice graph.
