EI {dy(x,t)/dx } +CA{d y(x,t)/dx}= summation of (F_o (sin(5nvt/r)sin(nwt)))  from n=1 to n= infinity

the derivative here are partial not ordinary

where EI, CA ,F_o , v ,r and w are constants 

This is a word file conatian a full discription for a partial differential equations please help me to solve it
