Solution book shows: [ f'(x) = \lim_h\to 0 \frac\frac1(x+h)^2 - \frac1x^2h ] [ = \lim_h\to 0 \fracx^2 - (x+h)^2h x^2 (x+h)^2 ] [ = \lim_h\to 0 \frac-2xh - h^2h x^2 (x+h)^2 ] Cancel ( h ): [ = \lim_h\to 0 \frac-2x - hx^2 (x+h)^2 = -\frac2x^3 ] Introduction to limits and derivatives, which are essential
