(a) cosw = cos(−340)

(b) cosw = sin 20

(c) sinw = cos(−10)

(d) sin w < − 1/2

(e) 1 < tanw

**Damon**, Monday, April 12, 2010 at 6:07ama cos 20

b cos (90-20) = cos 70

c sin (90 - -10) = cos -10 = sin 100

d 30 deg from x axis in quadrants 3 and 4 for -sin so below 210 and 330

e above 45 degrees in quadrant 1 and below 225 in quadrant 3
