Showing two overlapped lines in a plot?

Questions
1

I’m plotting two expressions and their lines happen to be the same. However, I want to show that they are two different lines. On the diagram, only the second line is visible because it ‘falls’ on the first one. How can I show that there are two different lines that just happen to be equal?

Make one of the lines thicker and plot that one first. Use the PlotStyle options with Thickness something like

PlotStyle -> {Thickness[0.01], Thickness[0.05], Thickness[0.05]}

You might have to play with the thickness values to get exactly what you want.

Thank you! That helped!

One more option:

PlotStyle -> {{Thickness[0.01], Blue}, {Thickness[0.02], Opacity[0.2],
     Green}, {Thickness[0.001], Opacity[0.9], Red}}]
