science vs engineering

Science student : "According to Hooke's Law, restoring force,F=-mg sin x = -kx"

vs

Engineering student : "According to Hooke's Law, restoring force, F=-mg sin x. Fortunately, x is sufficiently small in this situation, therefore I can derive an approximation, F=-mgx in order to simplify my calculation. The result is acceptable since I am allowed to have 5% error."

Science- What is true? What is the correct answer?
Engineering- First, what is the percentage error I am allowed to make. Secondly, what is the best, easiest, and simplest way to approach the the answer.

Maths Test..

I seriously think that I should buy a new alarm..

instead of using my phone as an alarm..

it's really annoying when you told yourself 

to wake up at 7..

but you always found yourself
still lying on the bed at 8....

lol..I set 6 alarms on my iphone..

so that if the first one cant wake me up..
I still have 5 more..
unfortunately when I woke up..

I found that all the alarms I set 

had been switched off!!!..

holy shit...

and the time was already 8.40..

I was supposed to sit in the class room by 8..

and I found myself lying on the bed at 8.40..

the exam had already began 40 minutes ago..

but luckily the prof allowed me to use the same amount of time

as what other students did..

finally..I ended up by doing the test in his office..

><!!!

well..this is my first time..

and I swear this is going to be the last time..

luckily I have a good prof..><.!!!!

I am sorry..I always fail to keep my promise..

ok..now..i gonna quit my facebook..

and concentrate on my study...

I dun wan to disappoint you again...

..

看着朋友们的毕业照
心里羡慕得很
但问了问自己，
到底是想要穿那件毕业袍，
还是想和朋友们共度
那值得纪念的一刻？
我心里很明白。
打了个电话回去，
纯粹为了祝贺
听见
“听说你是休业对吗?"
心里很不好受。
这也没办法
我们各自走着自己该走的路
往事只能回味，
我还有三个星期大考，
与其在此回忆过去，
倒不如珍惜现在，
为将来创造更美好的未来。
