You cannot.
sin(n)/n is an expression, not an equation. An expression cannot be solved.
Its just 8/n or 8 divided by n. You can't solve this problem because there is no other number to simplify or solve.
If sin2(theta) = 0, then theta is N pi, N being any integer
2n/3 = 4 2n = 3*4 2n = 12 n = 6 :)
sin x/(1+cos x) + cos x / sin x Multiply by sin x (1+cos x) =[(sin^2 x + cos x(1+cos x) ] / sin x (1+cos x) = [(sin^2 x + cos x + cos^2 x) ] / sin x (1+cos x) sin^2 x + cos^2 x = 1 = (1+cos x) / sin x (1+cos x) = 1/sin x
Do sin(x), square it, and then multiply it by two.
sinx=n/1 (1)sinx=n/1(1) sin(-n)x=n(-n) six=6

Its just 8/n or 8 divided by n. You can't solve this problem because there is no other number to simplify or solve.
5x = 80
sin(x)*sin2(x) = 1 so sin3(x) = 1 so that sin(x) = cuberoot(1) = 1 then x = pi/2 + n*pi where n is an integer.
If sin2(theta) = 0, then theta is N pi, N being any integer

It depends on the medium the light is passing through n sin I=n sin R
It depends what substance the refraction is taking place in. You need to know the refractive index, n then you can use the formula (sin(i))/(sin(r)) = n so sin(i) = n * sin(20) and i = arcsin ( n*sin(20) ) or, equivalently: i = sin^-1 ( n*sin(20) ) If you were using a glass block block, then n=1.5 and i = arcsin (1.5*sin(20)) = 30.86588247 = 30.9 degrees (3 s.f.)
