Hi all

I'm wondering if there is a way to solve for a function within an integral.

Specificly, I have something like this:

d[x] == Integrate[Sin[x + m[t]],t]

so I have function d, dependent on x, which is equal to the integral of
sin[x + m[t]] with respect to t, when m[t] is a function of t.

It looks sort of like a differential equation, but not really, and DSolve
didn't like it.  I thought about taking the derivative of both sides with
respect to t, but then the d[x] just goes completely away, and that can't
work.

Is this problem mathmatically possible, and if so, what kind of problem is
it (ie, ODE, Partial Differential Equations, something else) so I can go
look up a book on those types of problems, and finally, can Mathmatica solve
this type of problem?

Thanks

Steve
