We must find a pattern in the powers of 3:
So, as you can see, both and
end with 1. So, we can generalize as follows:
Since , we can deduce that
ends with 9.
Short answer: - 1
The first thing you should do is draw this or get a program to do it. I use desmos. It is included. The graph shows one complete cycle every 2*pi intervals (or 360 degrees.)
You will find no lower value that y = - 1 (nor any value greater than y = 1)
