I have a formula $A=-\frac{u'(a)}{u(a)}$ such that $u(a)=u(0)s(a)+u'(0)q(a)$ and $u'(a)=u(0)s'(a)+u'(0)q'(a)$ , I was asked to find the quadratic equation for $A$ ..
I know it means I have to find the coeffiecents $a$,$b$,and $c$ in the formula $aA^2+bA+c=0$ but I don't know how I can find them..I appreciate any help ..
