hey guys,

i have 2 maths problems that i am struggling with. Does anyone know how to do these two laplace questions

Find laplace of

d^2y/dt^t-13dy/dt+42y=6e^(-4t)

y(0)=0

y'(0)=3

and find the solution of the integral using laplace

f(t)=5+3t^2+2{f(u)sin(2(t-u))

the { is meant to be the integral sign

Thanks
