Using the definition of a derivative, we have:

$$f'(x) = \lim_h \to 0 \fracf(x+h) - f(x)h = \lim_h \to 0 \frac(x+h)^2 - x^2h = \lim_h \to 0 \frac2xh + h^2h = 2x$$ mathematical analysis zorich solutions

Since $x_n = \frac1n$, we have $|x_n - 0| = \frac1n$. To ensure that $\frac1n < \epsilon$, we can choose $N = \left[\frac1\epsilon\right] + 1$. Then, for all $n > N$, we have $\frac1n < \epsilon$. Using the definition of a derivative, we have:

However, obtaining solutions to the exercises and problems in Zorich's book can be challenging. The book does not provide solutions to all the exercises and problems, and students may need to seek additional resources to help them understand the material. Using the definition of a derivative
