(Intro 1 figure) A chandelier with mass m is attached to the ceiling of a large concert hall by two cables. Because the ceiling is covered with intricate architectural decorations (not indicated in the figure, which uses a humbler depiction), the workers who hung the chandelier couldn't attach the cables to the ceiling directly above the chandelier. Instead, they attached the cables to the ceiling near the walls. Cable 1 has tension T_{1}and makes an angle of theta_{1}with the ceiling. Cable 2 has tension T_{2}and makes an angle of theta_{2}with the ceiling.

Find an expression for T_{1}, the tension in cable 1, that does not depend on T_{2}.

Express your answer in terms of some or all of the variables m, theta_{1}, and theta_{2}, as well as the magnitude of the acceleration due to gravity g.

2. Relevant equations

T_{1}SHOULD equal: mg/ (sin theta 1 + (cos theta 1/cos theta 2)* sin theta 2), but any time I put in sin they say that I haven't formatted the equation right.

what am I missing that can only be computed by thetas 1 & 2 as well as m and g?
