The given function is [ f(z) = \frac{z}{4\cos^2 z - 1} = \frac{z}{(2\cos z - 1)(2\cos z + 1)}. ] Step 1: Find zeros of (f(z)) The zeros occur when the numerator (z = 0). So, the only zero is: [ z = 0. ] Step 2: Find singularities (poles) Singularities occur when the denominator (4\cos^2 z - 1 ______ _____ _______ _______ ___.
