Some one gets on to a ferris wheel 30^0 left of the bottom. What would be the phase shift if I am writing a sine Function?
Is it -120^0 or + 120^0. Please explain.

is the wheel rising or falling from that point?

It's turning counter clockwise.

so, it will achieve its minimum height when θ=30
sinθ achieves its minimum height when θ=270
sin(30+240) = sin(30-120)
the graph shows this.
