00:00I am going to start the question number two exercise one point one question number two
00:13so we have to prove that Z bar is equal to Z if Z is real
00:31so we have to prove that Z is equal to A plus Iota B
00:43so we have to prove that Z bar is equal to Z is equal to A plus Iota B
00:56so we have to prove that Z is equal to A plus Iota B
01:05so we have to prove that Z bar is equal to A plus Iota B
01:11so we have to prove that Z bar is equal to A minus Iota B
01:18so we have to prove that Z bar is equal to Z
01:29so Z you have to prove that A plus Iota B
01:33and Z bar is equal to A minus Iota B
01:37so we have to prove that A minus Iota B
01:46here plus Iota B plus Iota B
01:48here plus A minus Iota B
01:53here plus A plus iota B
01:56here plus A and minus Iota B
01:59So, this is B is equal to 0. So, this is real number. Okay. So, here we have to prove that Z is equal to Z, okay?
02:10So, this is the question number two complete.
