Sketch the graph of y=sin(x−30)y=\sin(x-30)y=sin(x−30) for x x\,x in the interval 0≤x<360∘0 \leq x < 360^\circ0≤x<360∘.
Given that x=60∘x=60^\circx=60∘ is one value for x x\,x in the interval 0≤x<360∘ 0 \leq x < 360^\circ\,0≤x<360∘ for which
sin(x−30)=k \sin(x-30)=k sin(x−30)=kfind the value of k k\,k and the other value of x x\,x in this interval.
