    Need help with Wronskian

    Let  y_1 and y_2 be nontrivial solutions of y'' - p(x)y=0. Suppose  W= \left(\begin{array}{cc}y_1&y_2\\y'_1&y'_2\end{arra  y}\right) is the Wronskian of  y_1 and y_2. Show that W is a constant.


    Do I need to find W'????

    Yes. Take the derivative of W with respect to x and show that it equals to zero.
