how to simplify



Dear group, I have an equation:

-(%e^(-log(e)*x-x)*((log(e)-1)*%e^x*sin(2*x)+2*%e^x*cos(2*x)+(-%
c*log(e)^2+2*%c*log(e)-5*%c)*%e^(log(e)*x)))/((log(e)^2-2*log(e)+5)*x)

I am hoping it is equal to a much smaller equation, how do I simplify
it? I have already used ratsim() and completeratsimp() (names?)

Thank you Michael Carey
