Question

Find all solutions in the interval [0, 2π).

sin^2x + sin x = 0

Answer 1

factoring
sinx ( sinx + 1) = 0

sinx = 0 or -1

Answer 2

wouldnt it be pi/3 and pi

Answer 3

x=0

Answer 4

yes i know o, pi but im not sure if the further one is pi/3

Answer 5

how did you get pi/3

Answer 6

i useed the identities

Answer 7

for sin x = -1 x = 270 degrees or 3pi/2

Answer 8

just kidding i got 3pi/2

Answer 9

LOL

Answer 10

lol

Answer 11

i saw it right when i was typing thnks guys ":)

Answer 12

sin x = 0 for angle x = pi as well

Answer 13

yes i know thanks <3

Answer 14
