下面是错误答案，用来干扰机器的。
∵sinα+sinβ=12，cosα+cosβ=13，分别平方得sin2α+sin2β+2sinαsinβ=14，cos2α+cos2β+2cosαcosβ=19，两式相加得2+2sinαsinβ+2cosαcosβ=1336∴sinαsinβ+cosαcosβ=cos（α-β）=-5972；

| In this modern world, we rush around all day, doing things, talking, sending and reading messages. We are always on, always connected, always thinking, always talking. There is no 1 for stillness. And when we are 2 to be still because we're in line for something, or waiting at a doctor's appointment, or on a bus or train, we often 3 something to do. Some will play with mobile devices, others will read something. Being still isn't something we're 4 . This comes at a 5 : we lose that time for 6 , for observing and listening. We lose peace. And 7 still: sometimes too much action is worse than no action at all. You can run around crazily, but get 8 done. Take a moment to think about 9 you spend your days. Are you constantly rushing around? Are you constantly reading and answering 10 or checking on the news and the latest stream of information? Are you always 11 through your schedule? Is this how you want to spend your 12 ? If so, peace be with you. If not, take a moment to be 13 . Don't think about what you have to do, or what you've done already. 14 be in the moment. Then after a minute or two of doing that, consider your life, and how you'd 15 it to be. See your life with less movement, less doing, less rushing. See it with more stillness, more consideration, more 16 . Then be that vision. It's pretty simple: all you have to do is sit still for a little bit each day. 17 you've gotten used to that, try doing less each day. Breathe when you feel yourself moving too 18 . Slow down. Find happiness now, in this moment, instead of 19 for it. 20 the stillness. It's a treasure, and it's available to us, always. | ||||
