 Hi and welcome to the session. I am Asha and I am going to help you with the following question that says, let z1 is equal to 2 minus iota and z2 is equal to minus 2 plus iota, find imaginary part of 1 upon z1 into z1 conjugate. Let us begin with the solution and first let us find z1 into z1 conjugate. Now z1 is 2 minus iota and its conjugate is 2 plus iota since for any complex number z cannot form a plus iota b and its conjugate will be a minus iota b which is also denoted by this sign. So now let us find the value of z1 into z1 conjugate which on applying the formula comes equal to 2 square minus iota square since a minus iota into a plus iota is equal to a square minus b square and here in place of a we have 2 and in place of b we have i. So 2 square minus i is forever just 4 minus minus 1 which is equal to 5. Now according to the question we have to find out the imaginary part of 1 upon z1 into z1 conjugate that is imaginary part of 1 upon 5. Now 1 upon 5 in the complex compound written as 1 upon 5 plus iota into 0 imaginary part of this complex number is 0 hence our answer is 0. So this completes the solution hope you enjoyed it take care and have a good day.
