Dear Pravin Nikam

how can resolve this equation ?

well at the end , we need to evaluate the parameters, which was obtained from the equations. Once you understand the physical meaning and its representation then very easy to resolve all the equation....Kindly refer the theory which will help you for understanding all the equations.
