    Question How to solve the equation x - sin(x) = (8Q)/(d^2 U) to x

    Hi guys,
    First off all, Q, d, U are all constants, wich means that the only variable is x, and it varies between [0, pi(3.1416...)]
    Secondly, I've already tried used the Newton's Raphson method, but I think I did something wrong(I searched on google how to, but it didn't work for me me).
    Lastly, I don't know how to program in VBA but I think it would be helpful to have a small program that's able to solve this kind of equaitions.
    Can anyone help me with this?

    Hi,

    One way would be to create a list of x values in A1:Ann

    and with Q in B1, d in B2 and U in B3

    then in C1 copied down

    but don't forget that trig functions use Radians for angles so if the x values are degrees then you'll need to convert them with =Radians()
