In this chapter, we shall define the Circular functions of Complex Numbers and then define new functions viz. Hyperbolic Functions. Later on, we will learn how to separate real and imaginary parts of functions of complex variables. We have divided this chapter into the following 4 categories: 

• Theory Lectures: Understanding the concepts behind the topics will help in the realization of what we are learning. It also forms the basis of problem-solving. So watch theory lectures before moving forward.


• Class A: In this class, we will solve problems based on direct applications of the definition of hyperbolic function and the use of basic identities of hyperbolic functions which we have discussed in the theory part.


• Class B: In this class, we will solve problems based on the relationship between circular functions and hyperbolic functions, use of hyperbolic identities in order to separate real and imaginary parts.


• Class C: In this class, we will solve problems related to inverse circular functions which are directly or indirectly related to hyperbolic functions.
