I need help with #5. Use the technique of Example 2 to determine the number of zeros of f in the first quadrant. 6. f(2)z6237 Example 2 Find the number of zeros of the function f(z) 23-222 4 in the first quadrant. Solution We examine f(z) on the contour shown in Figure 3.3; R is very big. On the segment 0 x R,f(x) = x3-2x2 + 4 is real and greater than 2. On the quarter- circle z = Re",...
