(Roll the mouse over the area above to see the corrections in blue) Explanations In the first mistake the quotient rule was not used correctly. The quotient rule is: In the mistake the numerator was taken to be just f'(z) - g'(z). Oops!
In the second mistake parentheses were not used around the g(z) part of the expression in the numerator, with the result that only the first part of g(z) was multiplied by f'(z). |
