To differentiate the function \( f(t) = \frac{2t}{4 + t^2} \), we will use the **quotient rule**, which is applied when differentiating a ratio of two functions.

The quotient rule states that if \( f(t) = \frac{g(t)}{h(t)} \), then:

\[
f'(t) = \frac{g'(t)h(t) - g(t)h'(t)}{[h(t)]^2}
\]

Here, \( g(t) = 2t \) and \( h(t) = 4 + t^2 \).

### Step-by-step solution:

1. **Differentiate the numerator** \( g(t) = 2t \):
   \[
   g'(t) = 2
   \]

2. **Differentiate the denominator** \( h(t) = 4 + t^2 \):
   \[
   h'(t) = 2t
   \]

3. **Apply the quotient rule**:
   \[
   f'(t) = \frac{(2)(4 + t^2) - (2t)(2t)}{(4 + t^2)^2}
   \]

4. **Simplify the numerator**:
   \[
   f'(t) = \frac{2(4 + t^2) - 4t^2}{(4 + t^2)^2}
   = \frac{8 + 2t^2 - 4t^2}{(4 + t^2)^2}
   = \frac{8 - 2t^2}{(4 + t^2)^2}
   \]

So, the derivative is:

\[
f'(t) = \frac{8 - 2t^2}{(4 + t^2)^2}
\]

### Tip:
When applying the quotient rule, always double-check the signs and terms in the numerator after differentiation to ensure correct simplification.
