1. sin(alph+beta)明明就等于sin（alpha）cos(beta) + cos (alpha) sin(beta), 不是相乘。。。

2. the math question on the sweets: is 21 right?

3. that question about sweet is a bit odd，5/3=1.3333 suggest that there is no sufficient paper to get 2 sweets, as if you use the remaining 5 papers to get sweet, you can only get 1. so it should be 15+5+1=21.
