basically...imagine a DNA but only a single helix =))))))...anyway...obviously sinxis a SINusoid...cosine is just a vertical graph of sinx so both are sinusoid

Yes, if you see the graph of $$y=\sqrt{x}$$ it's easy to note that it's not a sinusoid. you could use this site :http://www.wolframalpha.com/

The square root drawing only depicts the positive roots, imagine a similar curve on the left (quadrant II)
