Problem 44372. Polarisation
You have n polarising filters stacked one on top of another, and you know each axis angle. How much light gets passed through the filter bank? For more information, see Polarizer (Wikipedia).
>> n = [0, 90]; >> polarised([0, 90])
ans = 0

besides law of Malus (http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/polcross.html), also have a look at what happens to a third polarizing filter (http://alienryderflex.com/polarizer/)
Tip: In this problem, the first polarizer is always equated to 0.5 (since I_0 = 1 and the light comes from all directions): we should calculate the integral of the function cos(x)^2 from 0 to 2pi divided by 2pi (Mean Value Theorem). The remainder is Malus's Law.
This is actually a problem of physics, rather than programming.
