sin 30° tan 135° cos 45° / cos 60° sin 225° tan 150° Tolong bantu jawab ya...

nilai fungsi trigonometri

sin 30 = 1/2
tan 135 = tan(180-45) = - tan 45 = - 1
cos 45 = 1/2 √2

p = sin 30  tan 135 cos 45
p = (1/2)(-1)(1/2 √2)
p = -1/4 √2

cos 60 = 1/2
sin225 = sin(180+45) = - sin 45 = - 1/2 √2
tan 150 = tan (180-30) = - tan 30 =  - 1/3 √3

q = cos 60 sin 225 tan 150
q = (1/2)(- 1/2 √2)(-1/3 √3)
q = 1/12 √6

p/q = ( -1/4 √2)/(1/12 √6) 
p/q = - 1/2 √6
