Thread: 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.
