So this is going to be equal to one over pi, one over pi, not pi, my hand is not listening to my mouth, one over pi times sine of pi, sine of pi minus sine of, minus sine of pi times zero, which is just zero. Well sine of pi, that's zero. Sine of zero is zero. So you're going to have one over pi times zero minus zero. So this whole thing is just all going to be equal to zero. So this first part was 1 1 2. This second part right over here is equal to zero.
