Question
Evaluate the following expressions. (See the note above regarding power functions 2".)
(i) 3i#/3
(ii) (1+ i)'+i
(iii) (-ei)*i
Transcribed Image Text:Evaluate the following expressions. (See the note above regarding power functions 2".) (i) 3i#/3 (ii) (1+ i)'+i (iii) (-ei)*i
NOTE: Unless we say otherwisc, we will always use the "principal branch" (or "principal valuc") of the
power function 2“. This is defined using the principal logarithm Log via the formula
2° = e° Log z
Then f(z) = 2° is an analytic function whose domain is the set of all nonzero z for which Arg z + T.
