g(x) is a function of x that we do not know its form.(adsbygoogle = window.adsbygoogle || []).push({});

y(t) =(1/2) integral 0-->t [ sin(2t-2x)*g(x) ]dx

i tried to use integration by substitution and by parts

but the problem is that g(x) has an unknown form.

the actual problem is that

y" +cy' +dy = g(t) y(0) = y0 y'(0) = y'0

we are asked to find c,d,y0,y'0

knowing that y(t) is the solution of the second order differential equation.

i would appreciate your help.

Thanks,

Joe
