(t)*(dy/dt) - y = (t^3)(sin t) and then use initial value y(pi) = 0 to find the constant of integration the answer i got for C was ((pi^2) - 2)/pi can someone verify this for me?? and also the answer i got was y = (1/t)*[ (t^2)(cos t) + (2t)(sin t) - (2cos t) + C] i used the integrating factor method
