Sin(theta)theta = constant

    sin(theta)/theta = constant

    I have a value theta I am trying to solve for. Theta isn't limited to any value (it isn't an angle, actually a bunch of constants multiplied together). say I have
    sin(theta)/theta = b where b is another constant. Is there any way I can solve for theta=, in terms of b? I thought of taylor expanding the left hand side but then it just gets messy and I can't have an explicit value of theta....

    Unfortunately, there is no simple solution to that problem. You can get good approximations to the solutions (plural!) by graphing or by using numerical methods.
