**Trig Substitution:**

**For the following integral, which trig substitution is needed?**

\[ \int \frac{\sqrt{25x^2 + 4}}{x^4} \, dx \]

- ○ Tangent
- ○ Sine
- ○ Secant
- ○ Cotangent

---

*Explanation:*

The image presents a calculus problem involving an integral that requires the use of a trigonometric substitution method to solve. The integral in question is:

\[ \int \frac{\sqrt{25x^2 + 4}}{x^4} \, dx \]

Below the integral, four possible choices for the trigonometric substitution method are provided:
- Tangent
- Sine
- Secant
- Cotangent

Students are expected to choose the appropriate trigonometric function to simplify and solve the integral.
