A=11 Enter the value of antiderivative for X=0 and C=0. Keep 4 decimal
The handwritten notes appear to deal with integral calculus and involve the calculation of indefinite integrals using substitution methods. Below is the transcription of the text:

---

1. Integrate \( \int x \cdot 2 \ln(4x) \, dx \)
   - Let \( u = \ln(4x) \) 

2. For \( a = 11 \), find
   \[
   \int \sin(3ax) \cos(4ax) \, dx
   \]

   - Value of antiderivative, keep 4 decimals.

---

This text suggests finding the integral of two different expressions with specified operations and conditions. The first task involves a logarithmic function and implies the use of integration by parts or substitution. The second task involves trigonometric functions with a specific parameter \( a \) set to 11 and requires calculating the antiderivative to four decimal places.
