Question

Find all solutions to the equation.
sin^ 2x + sin x = 0

Answer 1

\[\sin ^{2}x + sinx = 0\]

Answer 2

x = 0 and x = arc sin (-1)

Answer 3

Can you show me your math?

Answer 4

sinx (1 + sinx) = 0
either
sinx = 0 or 1 + sinx = 0

Answer 5

That easy!?

Answer 6

correct

Answer 7

keep going

Answer 8

sin(x) = 0 implies x = pi*k where k is an integer
sin(x)=-1 implies x = 3pi/2 \(\pm\)2pi*k where k is an integer
