1)Solve the initial value problem
(dy/dt)+2y=20sin(t)+20cos(t) with y(0)=1.
Please teach me how to make it looks like something dy= something dt
2)Find a continuous solution for this first order linear IVP with discontinuous RHS:
My answer are y(t)=e^(t^2)+2 0≤t≤2 & y(t)=3e^-(t^2) t>2
Thanks
initial value problem?

the answer for 2) y(t)=2+(1/(e^(t^2))) 0≤t≤2
but how can I find the answer for t>2. Since I don't know what y is when t>2 , I could not find constant C.
