Answer 5

anybody?

Answer 6

\[\sin x=0=\sin 180 n\]
x=180n,where n is an integer

Answer 7

ok, that is a bit confusing to me :/

Answer 8

\[\sin x=-1=-\sin 90=\sin \left( -90 \right),\sin \left( 180+90 \right)\]

Answer 9

x=180n,n=....-2,-1,0,1,2...

Answer 10

ok but, thats not an option of answers :/

Answer 11

last one i see in your option. i.e.,x=-2*180=-360
n=-1,x=-1*180=-180
and so on for x=0,1,2

Answer 12

x=-90
x=270

Answer 13

correction
for n=0,1,2

Answer 14

oh! lol thanks. um, is that for the first one or the second one though?

Answer 15

-90,270 for second,
-360,-180,0,180,360 for first

Answer 16

thank you! you are a lifesaver!
