Why definite integral of undefined function returns unevaluated?

Why can Maple yield the result of int(q(t)*diff(q(t),t),t) = (q(t)^2)/2 (indefinite integral) but with int(q(t)*diff(q(t),t),t=0..t) (definite integral) it returns unevaluated? I expect the result of the definite integral to be (q(t)^2 - q(0)^2)/2.

How can I solve BVP for unknown boundary?

I have simple BVP for which one of boundaries is given as "L". My attempts to solve it gives various errors. One of the last attempts clearly shows that Maple "thinks" that L is rather another variable than unknown constant. de := diff(y(x),…
