```
var('x y')
k = 8/5
eqn = sin((k*x)^2+(k*y)^2) == cos(k^2*x*y)
implicit_plot(eqn,(x,-10,10),(y,-10,10),plot_points=1000)
```

Yes. The linewidth option works for me. The documentation is [here](http://www.sagemath.org/doc/reference/plotting/sage/plot/contour_plot.html#sage.plot.contour_plot.implicit_plot). Perhaps you haven't used it properly? Try making the last command: implicit_plot(eqn,(x,-10,10),(y,-10,10),plot_points=1000,linewidth=.1)

Can you give the precise code you used to plot this? The `thickness` parameter may be helpful, if I understand your question correctly.

I use implicit_plot which does not have a thickness option as far as I know. Changing plot_points and linewidths options doesn't seem to make any difference.

@dazedANDconfused answers this piece - we should probably standardize these names...
