Question

tan(180+0)....why the angle lies in third quadrant............???why we r giving weightage to 0......

Answer 1

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

Answer 2

i.e.tan(180) is in which quad????????

Answer 3

Siddharth, its not necessary that you will have to give weightage to the 0 degree

Answer 4

If you don't give that "weightage" you end up with the answer -0

Answer 5

Which is the same as 0

Answer 6

i m not concerned as to get correct answer........just wanna clear ma basics!!!!!!!!!!!

Answer 7

180 is not in a quadrant. It's on the x axis.

Answer 8

So is it clear now?

Answer 9

nope.........

Answer 10

just answer taht which quadrant 180 degrees lie in?

Answer 11

*that

Answer 12

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.

Answer 13

It doesn't lie in a quadrant. It is on the x axis.

Answer 14

Which quadrant is the negative x axis on?

Answer 15

Or you can also say it lies on \[i^2\]

Answer 16

cant really get....but thanx

Answer 17

What is it that you don't understand?

Answer 18

i wonder if the : tan(a +- b) makes a difference with it

Answer 19

hmmmm

Answer 20

probably not, but I havent ruled it out :)

Answer 21

so u guyz are a lil confused too.......

Answer 22

where did you get your "fact" that these are in quadrants?

Answer 23

i guess the sitution is same as we define the left and right side limit

Answer 24

:)

Answer 25

from trigonometry....................i think so

Answer 26

Siddharth you are not getting the tone of amistre

Answer 27

from a guy named trigonometry? or a textbook about trigonometry :)

Answer 28

every angle lies in a specific quadrant and that is 4 sure!!

Answer 29

Amistre meant that no one mentioned 180 degree lies in a quadrant

Answer 30

it may be bcoz amistre is a honourable man...nd i m a lad who has just started to widen his thinking

Answer 31

the angle 180 degree lies along the negative direction of x-axis not in a quadrant

Answer 32

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...

Answer 33

so..?

Answer 34

so we cannot define the y=o axis and the x = 0 axis as part of a specific quadrant

Answer 35

but we must be able to judge that which quadranr does 180 lies in..........

Answer 36

we must? why? it lies in the realm of the "0".. that is where it is :)

Answer 37

no quadrant...........

Answer 38

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

Answer 39

Sid. What quadrant is the negative x axis in? If you can answer that then you have your answer for 180 degrees.

Answer 40

suppose I do not have a nickel, and you do not have a nickel; why should we determine which of us has the nickel?

Answer 41

i can fit infinity on the head of a pin ;)

Answer 42

:)

Answer 43

sidd...the lines x = 0 and y = 0 divide the plane in four quadrants, so they are not the part of any

Answer 44

Good way of speaking @uzma

Answer 45

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..

Answer 46

and mam!!

Answer 47

yessssss

Answer 48

I agree

Answer 49

now u got it :)

Answer 50

90 is a measurement, not a place.

Answer 51

if the 90 gets you to the place, then you are where you are :)

Answer 52

yahooooooo!!!!!thanx a lot guyz

Answer 53
