Question 1027375
.
Find all the roots of (sqrt -1), leave the answer in polar form.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~



In his post, the other person presented the imaginary unit  ' i'  as the solution.


This answer is fatally incomplete.  {{{sqrt(-1)}}}   has two values:  i  and  -i.


In polar form,  these complex numbers are   ({{{1}}},{{{pi/2}}})    and    ({{{1}}},{{{3pi/2}}}).



Solved correctly.
