Sorry, I'm sure the questions i'm about to ask are simple to all of you out there but I really haven't had an easy time with Calc.
what is the limit as x approaches pi/2 from the left of
(tan x + 3)/tanē x
So I don't get it, when doing limits from the left and right are the procedures the same? Substitute in the limit, and if that becomes indetirminate use l'hospitals rule?
tan (pi/2) +3 would give me 3 and tanē x would give me 0. So i'd have 3/0 and thus this would be undefined and not indetirminate?
I'm really not confident in my answer and I would like to get this stuff down!!
Please help and thank you so much to every person who takes the time to assist me.
This is a no calculator question
you're right, I was thinking 1/0 = 0. So it'd signal a V. as. which would mean either pos/neg infinity?
so i'd pick a near by point to tell which one it would be, lets say 2pi/3 which would give me neg. radical three and since 1 rad = 0 it is getting more negative towards 90 degrees so from the left it would be approaching negative infinity?
is that correct?
