Write each expression in the standard form: a +bi.
(sqrt2 - i)^6
I found the radius to be sqrt3.
I used the sine function to find the reference angle, which is:
-sqrt3/3. However, I DO NOT recognize this fraction for sine. If I cannot find the reference angle, I cannot find theta, which I need to use in
De Moivre's Theorem.
