WebNov 15, 2016 · See that sum() was removed from expression f, because the multiplying constant was moved into the sum() and the D(sum()) = sum(D()). Also the first constant was removed because the derivative is 0. So: D(sum(-7645/2* log(pi) - 1/2 * log(w+a*y^2)) + (z^2/(w + a*y^2)) = D( constant + sum(f) + g ) = sum(D(f)) + D(g) Which should give: helmut kanter
