Topic: Area, e, and the Natural Log
1) Suppose c is a number such that area (1/x, 1, c) > 1000. Explain why c > 2^1000.
Hint: area (1/x , 1, c) = ln c

✔ 最佳答案
1)圖片參考：http://imgcld.yimg.com/8/n/HA00704496/o/701103220041113873393230.jpg
2)hence the arc length of a circle is 2*pi*r,the arc length of an arc that is x degrees is:
2*pi*r*(x/360)
3)hence the arc length of a circle is 2*pi*r,the arc length of an arc that is x radians:
2*pi*r*(x/2*pi)
=r*x
參考: Hope I can help you!
