Question

676 X 5

Answer 1

cos(theta) <0

Answer 2

sin(theta) is the y value on a unit circle, the tangent is the y/x value on a unit circle
(x,y) = (cos(theta), sin(theta))

Answer 3

and tan(theta) = y/x is negative

Answer 4

huh

Answer 5

what quadrant does that leave you in?

Answer 6

sorry, sin(theat) is the y value, and is positive, and cos(theta) the x value is negative

neg x value and pos y value

Answer 7

leaves you in the second quadrant, so between theta = 90 and theta = 180

Answer 8

\[-Tan(\theta) = \frac{ \sin(\theta) }{ -\cos(\theta) } = \frac{ + }{ - }\]

Answer 9

where
(x,y) = (cos, sin)

you have (-x,+y) ....second quadrant
