Question

Solve sin^3x=sinx
Does anyone know where to begin with this?
Can we go;
sin^3x-sinx=0
and use this? ;sinA-sinB=2cos(A+B/2) sin(A-B/2)

Answer 1

sin^3 (x) - sin (x ) = sin^2 (x)

Answer 2

@FaiqRaees where did you get the sin^2(x) from?

Answer 3

is the equation
\[\large\rm sin^3 x=sinx \] OR \[\large\rm sin^{3 x}=sinx \]

Answer 4

does x=45 degrees, x= 0 degrees?

Answer 5

yep

Answer 6

Okay! Thnks. I think I got it then.

Answer 7

oh no sorry
x = 0 and 180
