10.6.24 Analytic functions
Condition: Find all points at which the function \( f(z)=z \cdot e^{z \cos j} \) is differentiable. \( Z- \) complex value, \( Z_{\cos j}- \) conjugate value
Differentiation of analytical functions, finding their real and imaginary parts, finding the number of roots of complex equations using the argument principle, Roucher's theorem and much more in this section.
