what is i to the power of 359 equal to.
----------------------------------------
Recall that i^4 = 1
----------------------------------------
359 = (4*89 + 3)
-----------------------------------------
i^359 = (i^4)^89 *i^3
= 1^89 * i^3
= i^3 = -i

The powers of i go in a cycle of 4:

i%5E0+=+1

i%5E1+=+i

i%5E2+=+-1

i%5E3+=+i%5E2+%2A+i%5E1+=+-1+%2A+i+=+-i

i%5E4+=+i%5E2+%2A+i%5E2+=+-1+%2A+-1+=+1+=+i%5E0

and so on...

So, using integer division, divide 359 by 4 and find the remainder. i raised to the power of 359 is equal to i raised to the power of the remainder when 359 is divided by 4.
