1. Create a program for solving the equation $f(x)=0$ on the segment [A, B] up to $10^{-4}$
using the method of sequential approximation and dividing the segment in half.
2. Create a program for calculating values of the function $F(X,Z)$
for N values of X (with the start position $X_0$ and the step HX)
and for M values of Z (with the start position $Z_0$ and the step HZ).
3. Create a program for calculating sums of the series and values of the corresponding function
for the variable X (with the start position $X_0$, the end position $X_N$, and the step value H).
