    Solving a differential equation

    In order to write a program on change in global error using the Runge Kutta method tomorrow, i need an exact solution to this equation:

    y' = sqrt(sin(x) + ln(x)) with initial conditions x = 2, y = 4

    at the point x = 3.

    I could do this myself with Matlab but don't have the correct program at the minute.

    Cheers, Shaun.

    I think this is such a "simple" equation that you do not need Runga-Kutta method.

    A basic Simpon rule integration is sufficient to provide a solution.
