How do I make a sine wave in illustrator?

Hi,

 

I started a thread earlier this evening but I think that I accidentally flagged it as "solved" or something like that (I'm new to this forum). So I'm trying this again. I want to know if there's a way of creating a sine wave in illustrator. I've managed to create a cosine wave by using the zig zag effect on a line and choosing "smooth". But I can't seem to find a good way to make a sine wave.

 

This is the difference for anyone wondering:

I want a sine wave just like the picture above.

 

Thanks for the help!

    I think all the replies in the previous thread tried to say that the sine and the cosine curves are exactly the same

    Since there’s really no difference you could use a (probably rectangular) clipping mask to define where the wave begins and ends.

    Or, if you don’t mind expanding the effect, just do that and then edit (knife, scissors whatever) the path.

    if they are just the same but shifted along the x axis, you'd probably be best off applying a transform effect to move a copy of the original line whatever distance horizontally, then put a clipping mask on the result.

    ekmanch,

     

    As I (mis)understand it, to create a single full sine wave, you may:

     

    1) Create a horizontal line 2.5 times the length of the desired full sine wave (or you may adapt the length later);

    2) Effect>Distort & Transform>Zig Zag with 4 Ridges per segment and Smmoths Points and the desired height as the Size (or you may adapt later);

    3) Object>Expand Appearance;

    4) Object>Path>Add Anchor Points;

    5) With the Scissors Tool cut where the sine wave starts and ends;

    6) Ungroup if needed and delete the end bits (and adapt the length/height if needed).

    To make a sine wave you just wave and hope the sine waves back.

    Sorry folks. Gone midnight here.

    I missed that higher level effortless solution yesterday, Steve, because it was gone one here.
