Can you help with the last two,Fx' and Fy'

By using the Euler's identity: ei(theta) = cos(theta) + i*(sin(theta)) Show that 1. cos(theta) = (1/2)(ei(theta) + e-i(theta)) 2. sin(theta) = (1/2i)(ei(theta) - e-i(theta)) 3. cos(A-B) = cos(A)cos(B) + sin(A)sin(B) 4. sin(A-B) = sin(A)cos(B) - cos(A)sin(B)

Can you please explain the math after (149709.34) 1/2 to get 386.92 how did you get that

I got 0.0104891861 Nm for my answer and don't see how that is incorrect.

a)Define the term “standard candle” as used in cosmology.  b)The flux is defined asf(Dlum) = L/4πD^2lumwhere L is the absolute luminosity and Dlum is the distance to the radiation source (youmay assume z ≪ 1).Assume that we have measured the flux to be f = 7.234 10^−23 Wm^−2 and the absoluteluminosity is given by L = 3.828 x10^26W. Calculate the luminosity distance D lum to the objectin Mpc.
