Question

Evaluate the limit as x goes to pi/2:
sin(x)/(7x)

Answer 1

2/(7pi), just plug in the numbers

Answer 2

that's what I did, but thought there must be a trick some where

Answer 3

sin of pi/2 = 1 - correct?

Answer 4

yup, I guess since you have a lot of these limit problems the best way to do them is to first check to see if plugging in the number gives a real number. If not, you probably have to go back to some of the limit rules until you get to L'Hopital's rule of derivatives.

Answer 5

thanks, that def helps!
