Question

FInd the solution set for..help!

sin^2 x = sin x

Answer 1

not for help.

Answer 2

sin^2x - sinx = 0
sinx ( sinx - 1 )= 0
hence ,
sinx = 0 , and sinx = 1
x = 0 , pi, pi/2

Answer 3

sin^2x - sin x = 0 => sin x( sin x - 1) = 0
=> sin x = 0 or sin x-1 = 0 => sin x = 1.

Can you figure it out from there?

Answer 4

oh we factor it!

Answer 5

thanks @pgpilot326 @tanjeetsarkar96 :))

Answer 6

yep

Answer 7

inverse sine of 1 is 90. , why pi / 2 ?

Answer 8

90º = pi/2 radians

Answer 9

oh yeah, where did he get pi then ?

x = 0 , pi, pi/2

Answer 10

thats in radians .
