persamaan cosinus
-
The solutions set of cosx=1/2 ,0 < x < 360 is....
jawab:
cosx1,0 x360
cos x cos 60
(i)x 60 k.360
(ii)x 60 k.360
k = 0
(i)x60 0.360 60
(ii)x60 0.360 60(TM)
k = 1
(i)x60 1.360 420(TM) (ii)x 60 1.360 300 HP{60,300}
tugas 5: :
beberapa macam sudut bersesuaian
- sin x = sin (-x)
-cosx = sin(270 -x)
cosx = sin(90 +x)
- sin x = cos(90 + x)
-cosx = cos(180 -x)
sinx = cos(90 -x)
- tan x = tan (-x)
-cotx = tan(90 +x)
cotx = tan(90 -x) :
