Question

alright, need little help here:

Find limit:

Answer 1

testing

Answer 2

\[4\pi\]

Answer 3

just plug in 0 and evaluate

Answer 4

In this one you can actually just plug in zero for each of the x's. Start with the cos(x) and then the 5pi/sec(x). The cos(x) should give you 1 since cos(0) is 1, and the 5pi/sec(x) should give you 5pi since sec(0) = 1. Then from there you would just combine what you could.
