Question
how to find the square root of complex no?

for example -1+i

thank you

Answer
if your saying sqrt(-1 + i), then all i can say is, if you go to www.quickmath.com

click on Solve under Equations, then type in something like

x = sqrt(-1 + i)

the reason for the x = part, is because if you try solving for sqrt(-1 + i), it will tell you that you need a variable.

this will tell you what the sqrt(-1 + i) equals

for ex: sqrt(-1 + i) = .45509 + 1.09868i

sorry i don't know exactly how to solve it manually.
