i mean to say that.....tan(180+0) and tan(180-0) lie in 3rd and 2nd quadrant respectively ..why????......or u state in what quadrant they lie
anonymous
  • anonymous
i.e.tan(180) is in which quad????????
anonymous
  • anonymous
Siddharth, its not necessary that you will have to give weightage to the 0 degree

If you don't give that "weightage" you end up with the answer -0
anonymous
  • anonymous
Which is the same as 0
anonymous
  • anonymous
i m not concerned as to get correct answer........just wanna clear ma basics!!!!!!!!!!!
anonymous
  • anonymous
180 is not in a quadrant. It's on the x axis.
anonymous
  • anonymous
So is it clear now?
anonymous
  • anonymous
nope.........
anonymous
  • anonymous
just answer taht which quadrant 180 degrees lie in?
anonymous
  • anonymous
*that
anonymous
  • anonymous
If start on the x axis pointing in the positive x direction, and you rotate 180 degrees you will end up on the x axis pointing in the negative x direction.
anonymous
  • anonymous
It doesn't lie in a quadrant. It is on the x axis.
anonymous
  • anonymous
Which quadrant is the negative x axis on?
anonymous
  • anonymous
Or you can also say it lies on \[i^2\]
anonymous
  • anonymous
cant really get....but thanx
anonymous
  • anonymous
What is it that you don't understand?
amistre64
  • amistre64
i wonder if the : tan(a +- b) makes a difference with it
anonymous
  • anonymous
hmmmm
amistre64
  • amistre64
probably not, but I havent ruled it out :)
anonymous
  • anonymous
so u guyz are a lil confused too.......
amistre64
  • amistre64
where did you get your "fact" that these are in quadrants?
anonymous
  • anonymous
i guess the sitution is same as we define the left and right side limit
anonymous
  • anonymous
:)
anonymous
  • anonymous
from trigonometry....................i think so
anonymous
  • anonymous
Siddharth you are not getting the tone of amistre
amistre64
  • amistre64
from a guy named trigonometry? or a textbook about trigonometry :)
anonymous
  • anonymous
every angle lies in a specific quadrant and that is 4 sure!!
anonymous
  • anonymous
Amistre meant that no one mentioned 180 degree lies in a quadrant
anonymous
  • anonymous
it may be bcoz amistre is a honourable man...nd i m a lad who has just started to widen his thinking
anonymous
  • anonymous
the angle 180 degree lies along the negative direction of x-axis not in a quadrant
amistre64
  • amistre64
0 is a special number; it has odd behaviours that are not like the other numbers, therefore they = 0 line and the x = 0 line do not apply to a quadrant, they are outside of any quadrants and apart of all quadrants...
anonymous
  • anonymous
so..?
amistre64
  • amistre64
so we cannot define the y=o axis and the x = 0 axis as part of a specific quadrant
anonymous
  • anonymous
but we must be able to judge that which quadranr does 180 lies in..........
amistre64
  • amistre64
we must? why? it lies in the realm of the "0".. that is where it is :)
anonymous
  • anonymous
no quadrant...........
anonymous
  • anonymous
Actually the thing is obvious to those who are in contact with trigonometry for a long time. But to siddharth its like the case of georg cantor, questioning how big is infinity. Please don't take it personally, I am just joking
anonymous
  • anonymous
Sid. What quadrant is the negative x axis in? If you can answer that then you have your answer for 180 degrees.
amistre64
  • amistre64
suppose I do not have a nickel, and you do not have a nickel; why should we determine which of us has the nickel?
amistre64
  • amistre64
i can fit infinity on the head of a pin ;)
anonymous
  • anonymous
:)
anonymous
  • anonymous
sidd...the lines x = 0 and y = 0 divide the plane in four quadrants, so they are not the part of any
anonymous
  • anonymous
Good way of speaking @uzma
anonymous
  • anonymous
is it so.....that indirectly means that all angles of the form 90n (n is an integer) are not in any of the quadrant...m i right sir..
anonymous
  • anonymous
and mam!!
anonymous
  • anonymous
yessssss
anonymous
  • anonymous
I agree
anonymous
  • anonymous
now u got it :)
amistre64
  • amistre64
90 is a measurement, not a place.
amistre64
  • amistre64
if the 90 gets you to the place, then you are where you are :)

  • anonymous
yahooooooo!!!!!thanx a lot guyz
anonymous

chck out 4 ma new dobt!!

I must say siddharth, that these questions must never be burried in fear of being called an idiot
anonymous
  • anonymous
You did good by asking this question, and you should carry on asking such question
anonymous
