Hi. You can't integrate functions defined in a "complicate" way, this is: can't integrate functions with "if", other constructors and ... solve nor roots.

The workaround it's implement your own numerical integration procedure, or use a odesolver for get the numeric integral.

Best regards.
Alvaro.

Hi Razonar & Jean,

Thanks for the advice. I still cant find a way to rewrite the equations given there is k in both side of the equation to solve.

Need to solve the k in the function of w to continue calculation. Any suggestions is welcome.

Thanks

David

Hi Jean,

I don't understand much in your stuff !
As it looks we can integrate something in there.
Cheers ... Jean
