Right on you got it (:
And you did prove it
proof by substitution
Find lim as x -> 0+ (x)/(cosx)
If I plug in a really smaller number,
.001/cos(.001)
The top gets smaller and bottom goes to 1 so the answer is 0?
Is that correct? Anyone know anyway to prove it?
One more problem..
Find lim x -> 0+ (cosx)^[(1/(x^2)]
Much appreciation
