Lastly, we looked at the pattern with the powers of i by creating a table and rewriting the power with i^0, i, i^2, i^3, or i^4. We saw that we could rewrite this different ways and still have the same value. We demonstrated how to find these values by counting around in a circle with the 4 available outputs. Summary: even powers of i are 1 (divisible by 4) or -1 (not divisible by 4)
odd powers of i are i (when /4 the remainder is .25) or -i (when /4 the remainder is .75).
