    Can Anyone Solve this tough Algebra Problem?

    Solve for Unknowns of x1, x2, x3, x4

    -0.301Sin(x1)-0.501Sin(x1+x2)+0.08507Cos(x4)+0.315Cos(x4)= -0.4015
    0.301Cos(x1)+0.501Cos(x1+x2)-0.08507Sin(x4)-0.315Sin(x4)= -0.3015
    -0.08507Cos(62.8+x4)+0.501Sin(x1+x3)-0.501Sin(x1+x2)+0.08507Cos(x4)=0
    0.08507Sin(62.8+x4)-0.501Cos(x1+x3)+0.501Cos(x1+x2)-0.08507Sin(x4)=0

    Any hints or help to solve this problem is greatly appreciated.

    Thanks,

    I've always wondered about that phrase. Aren't paper and pencil "technology"? They don't grow on trees, they have to be manufactured!

    I guess I should have specified silicon chip technology rather than wood chip technology.
