looks like a basic sine wave with amplitude of 175 and period of 50 ...

$\displaystyle V(x) = 175\sin\left(\frac{\pi x}{25}\right)$

did you not read the first line in my post?

I recommend you research the role of the value $\displaystyle B$ in the equation $\displaystyle y = A\sin(Bx)$. - Nov 14th 2012, 05:28 PMahmedbRe: how to find equation?

how can you convert it to cos?

Pretty simply. $\displaystyle sin(u) = cos\left(\frac{\pi}{2} - u\right)$
