Use l'hopsital RUle to solve for
lim x>Pi / 4 5(1tanx)secx.
I solve for the equation (by plugging in pi/4) and I don't get zero, however, my answer is still wrong, should I still use the hospital rule?

Best ResponseYou've already chosen the best response.1\(\tan\left(\dfrac{\pi}{4}\right) = 1\) \(\sec\left(\dfrac{\pi}{4}\right) = \sqrt{2}\) 1) Never "plug in". Sometimes substitution is approprate. 2) This is not an indeterminate form. Please don't use l'Hopital's Rule. 3) Please supply the ENTIRE problem statement.

Best ResponseYou've already chosen the best response.1You can calculate in Light Years if you like. It's NOT an indeterminate form.

Best ResponseYou've already chosen the best response.1That doesn't mean we can't find the limit. We just can't use (or don't need) l'Hopital's Rule.
