Can this be solved?

  1. Sep 14, 2011 #1
    Hello,

    I have an equation which I am trying to solve for t. Of course the problem I'm having is due to the combination of ts within the argument of the sin term and also outside of it. I think I could also manage without the constant D (using sin(x)/x=sinc(x)), but that's no help here (as far as I can tell). Any advice is appreciated! Here's the equation:

    [tex]
    A \sin \left( B t \right) - C t + D = 0
    [/tex]

    Thanks,

    Kerry

    This is a transcendental equation which has to be solved numerically or graphically. First rewrite the equation with the sin term on the left and the linear term on the right:

    A sin(Bt) = Ct - D

    Now plot on the same graph, the function on the left and the function on the right. Their intersection gives the value of t which solves your original equation
