For such a simple case, you don't do it with Python, you do it with maths, and get an exact result. dC/dQ = 3*Q**2 - 30*Q + 93 d²C/dQ² = 6*Q - 30 The rule for differentiating polynomials of the form y = k*x**n is: dy/dx = (k*n)*x**(n-1) Consult a good calculus text book or on-line site for further details. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
