Hi. I have a few questions I am stuck on.
Evaluate each of the following limits.
1. lim (1-cosx)/ tanx
2. lim sinx/ (x+sinx)
And for the last one, #3, I am wondering If I have the right answer and the back is wrong. Take a look please.
3. lim (sin2x)/(2x^2+x)
My answer: 1
back of the book: 2
Please let me know. Thank you for your help!
