Question

sin^2x-2sinx=0

Answer 1

a) this is not physics
b)what do you get upon factoring this? we just did these together...

Answer 2

i got sinx=0 and sinx=2

Answer 3

and radians for sin=0 is pie and2pie

Answer 4

you phrase our answers strangely, so it is difficult to see whether you have the correct answer...
I assume you got to
\[\sin^2x-2\sin x=0\to \sin x(\sin x-2)=0\]which as you said means\[\sin x=0\]and \[\sin x=2\]
1) for what values of x is sinx=0
2)for what values of x is sinx=2
?

Answer 5

*should be OR sinx=2

Answer 6

so again...
1) for what values of x is sinx=0
2)for what values of x is sinx=2

Answer 7

absaluetly i got that after taht i am confused

Answer 8

you mean that you don't know for what x we have sinx=0 ?????

Answer 9

sin=2

Answer 10

that's the only problem for you?
when does sin x=2 ?????

Answer 11

i dont know in unit circle it is not there

Answer 12

that's because \[\sin x \le1\]so the answer is NEVER!

which means we only need to consider when \[\sin x=0\]so x=?

Answer 13

pie and 2pie

Answer 14

and...?

Answer 15

don't forget x=0...
