Hi, is there a way to take a derivative of a solution of equations?
For example,
var('p, alpha, beta, q, A, B, J, K') h=solve([p==alpha+2betaq, A-Bp==Jq, pq-K-alphaq-beta*q^2==0],p,q,J)
in the solution expressions for p,q,J, can I take a partial derivative of each with respect to A by adding some kind of an expression? Also, is there a effective way to simplify the results that I get for p,q,J?
