**What is a complement of a set and example?**

What Is the Complement of a Set? The complement of set A is defined as a set that contains the elements present in the universal set but not in set A. For example, Set U = {2,4,6,8,10,12} and set A = {4,6,8}, then the complement of set A, A′ = {2,10,12}.

**What is the complement of the function?**

The complement will be f’ = (x’ + y)(x’*(y+z’))(y). To find the complements of a boolean function, we apply de morgan’s law . 1) We change the OR gates with the AND gates and the AND gates with the OR gates. 2) We change each literal in the function such that it becomes its complement.

**What is the difference between absolute complement and relative complement?**

Complement (Absolute), denoted c, refers to the elements that are not in the set. In the example, Dc = {a,c,e,i}. Complement (Relative), denoted \\, refers to the elements that are in the first set, but are not in the second set. In the example, H \\T = {c,f }.
