Question

Find the solutions for x^2+1=0.

Answer 1

\[x^2=-1\] is a start

Answer 2

\[x^2 +1=0 \]
\[x^2=-1\]
\[x=i\]

Answer 3

Is the solution just i or -i as well?

Answer 4

\[i=\sqrt{-1}\]

so -i would actually be
\[-\sqrt{-1}\]

Answer 5

@idealist hey girl, this question from which part? complex matrix? be careful with it, it links to Euler's formula for the solution of ODE

Answer 6

Yes, I will.

Answer 7

ok
