You're given the "a" to use. You only need to figure out the relationship between "k" and "p". The relationship is:
k+=+p%2F%282pi%29
Substituting your "p" (period) into this we get:
k+=+%28%283pi%29%2F2%29%2F%282pi%29+=+%28%283pi%29%2F2%29%2A+%281%2F%282pi%29%29+=+3%2F4
So your equation is:
y+=+%281%2F2%29sin%28%283%2F4%29x%29
