Evaluate the limits (trigonometric)

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

by applying l'Hospital rule I get

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

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

$\displaystyle 7 * -\infty $,

$\displaystyle - \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.

Anyone stupid enough to fall for you scam deserves the outcome.

I can find no entry for you at MathGenealogy Project

So what equips you to tutor?

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

Re: Evaluate the limits (trigonometric)

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.
