When we evaluate it at 1, we do this in this green color. That's not the green color I thought I was going to do. When you evaluate it at 1, you get 1 squared over 2, which is 1 half, and then you get 1 to the 3 halves, which is just 1. This becomes minus 4 thirds, and then you have plus 1. Let's simplify this, and I'll do it all in the same color now. This is going to be equal to pi times 4 squared over 2, that is 16 over 2, which is equal to 8. Then you have 4 times 8, which is 32 over 3, so minus 32 over 3 plus 4.
