Hello Narasimham,
I'd try
<<Graphics`ComplexMap`
CartesianMap[Sin,{-Pi/2,Pi/2},{-Pi/2,Pi/2},Lines->{11,11}];
but to get your approach to display nicely (and simplify it a bit):
<<Graphics`Graphics`
DisplayTogether[
Block[{$DisplayFunction=Identity, equidist=Pi* Range[-5,5]/10},
Join[ParametricPlot[Through[{Re,Im}[Sin[#+I*t]]],{t,-Pi/2,Pi/2},
PlotPoints->61]&/@equidist,
ParametricPlot[Through[{Re,Im}[Sin[t+I*#]]],{t,-Pi/2,Pi/2},
PlotPoints->61]&/@equidist]
],AspectRatio->Automatic
]
I hope this helps,
Peter
