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.

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
