Question

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

A. x= +/- pi(n), x= pi/2 +/- 2pi(n)

B. x= pi/2 +/- 2pi(n), x= 3pi/2 +/- 2pi(n)

C. x= pi/3 +/- 2pi(n), x= 3pi/4 +/- 2pi(n)

D. x= +/- pi(n)

Answer 1

A

Answer 2

Can you show me how to solve it

Answer 3

when sinx=0 x=pi
when sinx=1 x=pi/2
because there are infinite solutions so you add +/- 2pi n

Answer 4

thank you :)
