(f'(a) = \lim_h \to 0 \fracf(a+h)-f(a)h), provided the limit exists.

A: Ethically, no. Legally, no (unless it is a DRM-free purchased copy with sharing rights). Instead, ask them to buy their own or use a library copy.

[ \lim_x \to 0 \frac\sin xx = 1,\quad \lim_x \to 0 \frac\tan xx = 1,\quad \lim_x \to 0 \frac1-\cos xx^2 = \frac12 ] [ \lim_x \to 0 \frace^x-1x = 1,\quad \lim_x \to 0 \frac\ln(1+x)x = 1,\quad \lim_x \to \infty \left(1+\frac1x\right)^x = e ]
