# Math Help - Evaluate the limits (trigonometric)

1. ## Evaluate the limits (trigonometric)

I have such a limit $\lim_{x \to{\pi/2}^+}{7cos(x)}/{1-sin (x)}$ which is of type 0/0

by applying l'Hospital rule I get

$\lim_{x \to{\pi/2}^+}{-7sin(x)}/{-cos(x)} =$,

$7 *\lim_{x \to{\pi/2}^+}{tan(x)} =$

$7 * -\infty$,

$- \infty$, and it makes sense for me by visualizing the graph,

what do you think?

This graph ]does agree.

L'hopitals Rule is a great way to solve these limit problems.

from my experience on forums I prefer to ignore the advertising messages - makes my life easier

Me too. I do not like advertising messages. I prefer receiving emails from people like myself who are the highest possible level of math aptitude for help. Very few people can be trusted and definitely few have the math background that I possess.
