when i write :

I want answer me   '2'

but it answer on this way:

what i should do for it answer just '2' and ynderstand dont need conjugate 'x and lambda'

How can i solve below equation?

diff(v,x,x)+diff(v,x)*cot(x)-v(cot²(x)+nu)=a²Q/D

that Q is function of x

Q=Q[x]

I know if we want calculus derivative of function use of command diff in maple. now i want know if want calculus variation of functional what we should do? is there any special command?
