    problem by laplace

    an emf Esinpt is applied at t=0 to a circuit containing a capacitance C and inductance L.the current I in the circuit satisfies the equation Ldi/dt+(1/C)(integration)(idt)=Esinpt.If p^2=1/(LC) and initially the current i and charge q are 0.Show that the current at time t is (Et/2L)sinpt by laplace

    i am not getting t rest all i am getting

    please help
