Solve 0<=Theta<2pi
hey
hey can you solve for sin(theta + 2pi/3)
brb
i got sin(theta+2pi/3)=1/2
plz ignore me im sleepy not in a moO_Od to do math rn :( and my brain isn't working :(
its fine :)
surji can you help me?
\[\sin \left( \theta+\frac{ 2 \pi }{ 3 } \right)=\frac{ 1 }{ 2 }=\sin (2 n \ pi+\frac{ \pi }{ 6 }),\sin \left( 2 n pi+\pi-\frac{ \pi }{ 6 } \right)\] \[\theta=2n \pi+\frac{ \pi }{ 6 }-\frac{ 2 \pi }{ 3 },2 n \pi+\pi-\frac{ \pi }{ 6 }-\frac{ 2 \pi }{ 3 }\] where n is an integer. \[\theta=2n \pi-\frac{ 3\pi }{ 6 },~or~\theta=2 n \pi-\frac{ \pi }{ 2 }\] put n=1 \[\theta=2 \pi-\frac{ \pi }{ 2 }=\frac{ 3 \pi }{ 2 }\] \[\theta=2 n \pi+\frac{ 6 \pi-\pi-4 \pi }{ 6 }\] \[\theta=2 n \pi-\frac{ \pi }{ 6 }\] put n=1 \[\theta=2 \pi-\frac{ \pi }{ 6 }=\frac{ 11\pi }{ 6 }\]
