Final answer:
To compute the given equation, you need to find the second derivative of y(t), the first derivative of y(t), and the value of y(t) itself. Once you have these, substitute them into the equation and perform the necessary calculations.
Step-by-step explanation:
The given equation is l[y](t) = y''(t) - 3ty'(t) 3y(t). To compute this equation, we need to find the second derivative of y(t) (denoted by y''(t)), the first derivative of y(t) (denoted by y'(t)), and the value of y(t) itself. Once we have these, we can substitute them into the equation and perform the necessary calculations.
