Trying to simplify an expression with Maxima



Hi,

LB:(R2-R1m+b1-b2/2)/(cos(beta1)+cos(beta2));
d:diff(LB);

I obtain an expression where clearly 1/(cos(beta1)+cos(beta2)) is a
common factor to all terms, and can be collected. Why neither ratsimp
or fullratsimp are able to perform this operation? thanks
