The student can work the problems at the end of Chapter II by the method of differentials. For further practice, if desired, the following examples are appended. $$ u=\left(x^{2}+1\right) \sqrt{x^{3}-x} $$
If \(\beta\) and \(\gamma\) are infinitesimals of the same order, show that their sum is, in general, an infinitesimal of the same order.
Differentiate each of the following functions by the method of differentials, and test the result by the methods of Chapter II. $$ z=\frac{1+x+x^{2}}{2 x} $$
