Seth, in Judaism, Christianity, Mandaeism, Sethianism, and Islam, was the third son of Adam and Eve and brother of Cain and Abel, their only other child mentioned by name in the Hebrew Bible. According to Genesis 4:25, Seth was born after Abel's murder by Cain, and Eve believed that God had appointed him as a replacement for Abel.
Want to understand how set C contains ##N## x H. H is only defined to be a set with element e and as the domain/range of function k. Is this enough information to conclude that the second set in the cartesian product W is H and not a subset of H?
My thinking is to show that ##N## and H satisfy...
Hello all,
The question I am tackling is as follows:
I was wondering if any of you could look over my solution and tell me if my logic is correct.
Any feedback would be great!
For this,
I am trying to understand why the set ##(0,2)## has no maximum. Is it because if we say for example claim that ##a_0 = 1.9999999999## is the max of the set, then we could come along and say that ##a_0 = 1.9999999999999999999999999999## is the max, can we continue doing that a...
In the context of the mappings of a set S into itself, when S is not number system with a zero, what is the customary definition for "zero mapping"?
( ChatGPT says that its a mapping that maps each element of S to some single element of S , i.e. maps all elements to some constant. )
