Derive Eq. 2.25. Hint: Use Eqs. (3) and (4) from Example 2.11 to express iE as a function of iB. Solve Eq. (2) for i2 and substitute the result into both Eqs. (5) and (6). Solve the "new" Eq. (6) for z'i and substitute this result into the "new" Eq. (5). Replace iE in the "new" Eq. (5) and solve for iB. Note that because iCc appears only in Eq. (1), the solution for iB involves the manipulation of only five equations.
