Question

Describe the difference between an angle with a positive and an angle with a negative measure

Answer 1

This is trig?

Answer 2

^you gonna delete that now, lagrange? trololo.

Answer 3

wow man chill out, whats your deal

Answer 4

precaculus

Answer 5

okay, well then we can talk about positive and negative angles with reference to the unit circle

Answer 6

my deal is you making smartass comments on every question, which wastes everyones time. How about getting straight to the answer?

Answer 7

kthanksbye.

Answer 8

anyway, we can think of an angle basically as a rotation of a line that begin on the x axis

Answer 9

now, if we think of that this way, we logically conclude that a positive angle increases through the 1st, 2nd, 3rd and 4th quadrents

Answer 10

now what can we conclude of about a negative angle, well a negative angle would in turn decrease throught the 1st, 2nd , 3rd and 4th quadrents

Answer 11

i mean, decrease through the 4th, 3rd, 2nd and 1st quadrents

Answer 12

is that okay?

Answer 13

I don't know

Answer 14

The negative simply tells you that you're rotating the angle clockwise (opposite to normal).

\[-\theta = 360 - \theta\]

Answer 15

Really need pictures to illistrate :S

Answer 16

and positive tells you that you are rotating counterclockwise

Answer 17

ty

Answer 18

This picture illistrates the differences...

Answer 19

illustrate even :)

Answer 20

what I say?
+ , _ angle?

Answer 21

My answer would be what i said in my first reply. Well i'd mention the cartesian plane too.

How i'd answer it...
"The negative sign tells you that the angle is being rotated clockwise (opposite to normal) through the cartesian plane.

\[-\theta = 360 - \theta\]"
