I want the right coding for ploting a horizontal line with sin wave

Pl I want the code of plotting horizontal line with sin wave in the same figure

[John D'Errico]

Since this is surely homework, what have you tried? If nothing, why not?

1. Surely you can you plot a sine wave?
2. Can you plot a horizontal line? Hint, either use plot, or use yline.

If you will use plot to plot both of the curves, then you need to use hold on to force the second plot to overlay the first. But yline does not require you to use hold.

I know how to plot sin but I could put the horizontal line with it I don’t know how to code it

Perhaps it's hold you may be unaware of????

Again, "show your work!"

Hello!

hold on
plot([x1,x2], [y,y])

Line starts in [x1, y] point and ends in [x2, y] point.
