I don't understand what you want. When you have compound fractions, of the sort: [1/(x + h + 3) - 1/(x + 3)] / h, that last h is a factor of the denominator you get up above in the numerator for the final fration: [x + 3 - x - 3 - h] / h(x + 3)(x + h + 3)...in general, (A/B)/h = A / Bh<br><b>References : </b><br> Where are those fractions in the numerator?
