Given the following expression F:
(C1) F : - G1*x6 - 2*a1*DD1*%E^(-2*a1*x4)*(%E^(a1*x4) - 1) - chi*(1-x1)/2;
a1 x4 - 2 a1 x4 chi (1 - x1)
(D1) - 2 a1 DD1 (%E - 1) %E - G1 x6 - ------------
2
I am trying to factor E^(-a1 x4) out of the first term, to get:
- a1 x4 - a1 x4 chi (1 - x1)
...) - 2 a1 DD1 (1 - %E ) %E - G1 x6 - ------------
2
- a1 x4
so as to be able to replace %E with one symbol A
Any suggestions to perform such factorization?
thank you
