CSIR NET MATHEMATICS DEC 2017 | Complex Analysis | Zeros of Complex Function f(z)

This video provides a step-by-step mathematical solution to a complex analysis problem from the CSIR NET December 2017 exam. The goal is to determine the number of zeros for the complex function $f(z) = e^z + e^{-z}$. Through algebraic manipulation and the use of Euler's formula, it is demonstrated that the function possesses infinitely many zeros.
