What if we take sqrt(i) = (1+i)/sqrt(2) and sqrt(-i) = - (1-i)/sqrt(2) and obtain sqrt(i)+sqrt(-i) = + 2i/sqrt(2) = sqrt(2)xi ? Or we take sqrt(i )= - (1+i)/sqrt(2) and sqrt(-i) = (1-i)/sqrt(2) and obtain sqrt(i)+sqrt(-i) = - 2i/sqrt(2 )= - sqrt(2)xi ?
Your answer is the correct one. He should have added the principal square roots which are the first ones you find in counter clockwise. If you use polar form and always take the counterclockwise angle this mistake wouldn’t occur. The answer shall be isqtr2 which is purely imaginary
very easy to understand and very helpful. but please could u kindly explain why we used the curly bracket at the end. i mean, is that what is used to signify an absolute value in notation.?
