How to manage the absolute value on a differential equation $|T(x)'+A(T,x)+B(T,x)| = f(T,x)$
Hi every person I require to address a formula of this type:
$|T(x)'+A(T,x)+B(T,x)| = f(T,x)$
with borders problems.
The absolute value is my trouble. Certainly without it, the remedy of these is well dealt with in the literary works.
So, can I do the very same procedure? Or there is an additional means to address this? Many thanks.
