If I want to simplify an extremely large algebraic expression which equals zero to a simple neat equation -- how do I do that in Mathematica (or symbolic package of Matlab). Giving you an example of the equation below:
(c1 (-1 + E^(I dx kx)) (-1 + v4))
--------------------------------------------------------
(-1 - 6 c1 c2 v1 + 6 c1 c2 v1 Cos[dx kx])
(c1 (-1 + E^(I dx kx)) (-1 + v4))
+ -------------------------------------------------------
(1 + 6 c1 c2 v1 - 6 c1 c2 v1 Cos[dx kx])
(4 c1 c2 (-1 + v4) (-1 + Cos[dx kx]))
- ----------------------------------------------------------- = 0
(-1 - 6 c1 c2 v1 + 6 c1 c2 v1 Cos[dx kx])
In fact my equation is much more larger than this. Thank you
(c1 (-1 + E^(I dx kx)) (-1 + v4))
--------------------------------------------------------
(-1 - 6 c1 c2 v1 + 6 c1 c2 v1 Cos[dx kx])
(c1 (-1 + E^(I dx kx)) (-1 + v4))
+ -------------------------------------------------------
(1 + 6 c1 c2 v1 - 6 c1 c2 v1 Cos[dx kx])
(4 c1 c2 (-1 + v4) (-1 + Cos[dx kx]))
- ----------------------------------------------------------- = 0
(-1 - 6 c1 c2 v1 + 6 c1 c2 v1 Cos[dx kx])
