Find the exact solutions to each equation for the interval 0

OpenStudy (anonymous):

Divide each side by sin x

OpenStudy (anonymous):

so its cos x=0?

OpenStudy (anonymous):

no cosx=1

OpenStudy (anonymous):

which means that x=0 or 2*pi right?

OpenStudy (anonymous):

wow.... 0<x<2pi... no = if that is the case => no solution

OpenStudy (anonymous):

the problem states that x is greater than or equal to 0. so i would assume its 0. i just couldnt add in the equal to symbol

OpenStudy (anonymous):

next time type: >= or <= everybody will understand :) if <= then 2 solutions: 0 and 2pi

OpenStudy (anonymous):

okay thanks for the tip and answer

OpenStudy (anonymous):

welcome!

sinxcosx=sinx sinxcosx-sinx=0 sinx(cosx-1)=0 sinx=0 cosx-1=0 sinx=0 cosx=1 x=0 x=0 x=pi x=2pi x=2pi

myininaya (myininaya):

OpenStudy (anonymous):

isnt it just 0 and 2pi?

myininaya (myininaya):

OpenStudy (anonymous):
