I've tried and asked my friends and no one knows how to start this.
Start by getting an expression for f(h). Then get f(0). Then get f(h) - f(0) and simplify. Then divide the result by h. Then take the limit. Alternatively, recognise the value of the limit as f'(0).
See the approach I advised for the first question. Alternatively, recognise the value of the limit as f'(1).
