Question

Please help!! Dx
Solve sin(x)(sin(x)-1)=0

Answer 1

sin x = 0 or sin x = 1
x = 0,180,360 or x = 90,270

Answer 2

x = 90 only not include 270, sorry

Answer 3

\[
\sin(x) =0 => x = 2 k \pi, \,\,k=0, \pm 1, \pm2 \cdots

\]
\[
\sin(x) =1 => x = \frac \pi 2+2 k \pi, \,\,k=0, \pm 1, \pm2 \cdots

\]

Answer 4

Choose the k above to fit your interval for x
