eqn = a Exp[I k x] + b Exp[I k x] == 0;
eqn // Simplify
(a + b)*E^(I*k*x) == 0
eqn // Factor
(a + b)*E^(I*k*x) == 0
eqn // Together
(a + b)*E^(I*k*x) == 0
eqn // Collect[#, Exp[I k x]] &
(a + b)*E^(I*k*x) == 0

=============
Hello,
I'm trying to solve a PDE using a Exp ansatz.
Now I am am stuck with the equation of the form
a Exp[I k x] + b Exp[I k x] == 0 (though much more complicated)
What I would like to do is a comparison of coefficients. How can I make
Mathemetica to show me a form of the equation where I can easily read
the comparison equations?
(In the above equation
(a + b) Exp[I k x] == 0
for example.)
Regards
