dy/dt = y*t^2 + 3*y
y(0) = 1
t= 0:2
This is the equation which I want to integral
But when I integrate and plot this how can I get dy/dt. Because dy/dt becomes y when i intergrate it.

I don't have idea to do this with function int or integral

syms y(t) c
eqn = diff(y) == y*t^2 + 3*y
eqn(t) = 
ic = y(0) == 1
ic = 
sol = dsolve([eqn, ic])
sol = 
fplot(sol, [0 2])
