Make subject of formula

  1. Help me make θ the subject of the formula in the following equation:

    X = [cosθ + R(V-θ)-1.6364]-1]

  3. Het otakwa and welcome to the forums. I'll assume your equation is X = [cosθ + R(V-θ)^-1.6364] - 1.

    The question I have for you is are you aware that you will only be able to get a value for θ to be in the range of [0,pi] and with the R and V it might even be more restricted.

    For this particular equation you won't be able to get an analytic answer and you will need to use a computer to get the answer.

    Have you ever done this kind of thing before?
