Solving the Equation x = (1.66x10^28)/(sin^3(45)) for Binary Star Mass

Homework Statement

Solve the equation x = (1.66x10^28)/(sin^3(45))

Homework Equations

n/a

The Attempt at a Solution

My attempt is really non existent, since I haven't had to work with sin^3 before, I haven't even seen it before this assignment. Basiclly I'm working out the mass of a binary star using the sin^3 method, and this is the last stage. The rest of the question has nothing to do with this bit I'm stuck on, so I don't think it's worth posting. Can anyone tell me how I'd go about solving this equation? Thanks!

Isn't $$sin^3(A) = sin(A)*sin(A)*sin(A)$$ ?

You should be able to just calculate x with your calculator, I believe...

Haha, not my brightest moment ever. Thanks for clearing that up!
