# Math Help - A question about vertical asymptotes of a trigonometric function...

1. ## A question about vertical asymptotes of a trigonometric function...

Why is there no vertical asymptote at t = 0?

2. ## Re: A question about vertical asymptotes of a trigonometric function...

simply because lim f(x) =x(cosx)/sinx as x tends to zero is equal to 1 and not + or - infinity as required by the vertical asymptote....

I see, that makes perfect sense. Thanks heaps
