The text extraction wasn't very clear. However, based on the visible parts, it seems we need to integrate the following functions:

1. \( \csc(4x+3)\cot(4x+3) \)
2. \( \frac{1}{(2x+3)^3} \)
3. \( \frac{1}{3x+2} \)
4. \( \csc^2(7-11x) \)
5. \( e^{6-4x} \)

Let's find the integrals for each of these functions:

### a) \( \csc(4x+3)\cot(4x+3) \)
The integral of \( \csc(u)\cot(u) \) is \( -\csc(u) \). Let \( u = 4x + 3 \).

\[
\int \csc(4x+3)\cot(4x+3) \, dx = -\csc(4x+3) \cdot \frac{1}{4} + C = -\frac{1}{4}\csc(4x+3) + C
\]

### b) \( \frac{1}{(2x+3)^3} \)
Use the substitution \( u = 2x + 3 \), hence \( du = 2dx \).

\[
\int \frac{1}{(2x+3)^3} \, dx = \int \frac{1}{u^3} \cdot \frac{du}{2} = \frac{1}{2} \int u^{-3} \, du = \frac{1}{2} \cdot \frac{u^{-2}}{-2} + C = -\frac{1}{4(2x+3)^2} + C
\]

### c) \( \frac{1}{3x+2} \)
Use the substitution \( u = 3x + 2 \), hence \( du = 3dx \).

\[
\int \frac{1}{3x+2} \, dx = \int \frac{1}{u} \cdot \frac{du}{3} = \frac{1}{3} \int \frac{1}{u} \, du = \frac{1}{3} \ln|u| + C = \frac{1}{3} \ln|3x+2| + C
\]

### d) \( \csc^2(7-11x) \)
The integral of \( \csc^2(u) \) is \( -\cot(u) \). Let \( u = 7 - 11x \).

\[
\int \csc^2(7-11x) \, dx = -\cot(7-11x) \cdot \frac{1}{-11} + C = \frac{1}{11}\cot(7-11x) + C
\]

### e) \( e^{6-4x} \)
Use the substitution \( u = 6 - 4x \), hence \( du = -4dx \).

\[
\int e^{6-4x} \, dx = \int e^u \cdot \frac{du}{-4} = -\frac{1}{4} e^u + C = -\frac{1}{4} e^{6-4x} + C
\]
