This question has to do with binary star systems, where i is the angle of inclination of the system.
Calculate the mean expectation value of the factor $\sin^{3}$ i, i.e., the mean value it would have among an ensemble of binaries with random inclinations. Find the masses of the two stars, if $\sin^{3}$ i has its mean value.
Hint: In spherical coordinates, $(θ, ϕ)$ , integrate over the solid angle of a sphere where the observer is in the direction of the z-axis, with each solid angle element weighted by $\sin {3} (θ)$ .

Plot the given point $(- 4, 0)$ in a rectangular coordinate system.

When you’re starting with the coordinate system equations, you will have to think differently and apply the factor of probability in your statistical data and estimation tasks. It is exactly where you have to apply alternate coordinate systems to compare more than two approaches. You can see coordinate system examples that will help you to find the answers to statistical challenges. You can also use so-called polar coordinates when you are dealing with the different dimensions. Be it Cartesian coordinate system or Homogeneous solutions, always check several examples to see what solution will fit you in the best way possible.
