mary, a parent:

i was trying to find the limit of this problem

the limit as x approches infinity of x minus cosx divided by x

lim x-cosx/x x->oo

Hi Mary,

For any x, -1 ≤ cos x ≤ 1 and hence -1/x ≤ cosx/x ≤ 1/x lim -1/x = lim 1/x = 0 as x -> infinity and hence you can apply the sandwich theorem.
