I am not really sure what you are asking but I don't think that equation holds true anywhere.

$\displaystyle

\cos (u) = \sin (v)

$

only when $\displaystyle

u = v + \pi /2

$

$\displaystyle

\begin{gathered}

u = \sin (x) \hfill \\

v = \cos (y) \hfill \\

0 \leqslant u \leqslant 1 \hfill \\

0 \leqslant v \leqslant 1 \hfill \\

u \ne v + \pi /2 \hfill \\

\end{gathered}

$
