Alright, I need to solve this problem involving integral equations and constants. Let's break it down step by step to ensure I understand everything correctly.

First, the problem provides an integral equation with constants $$ a, b, c, d, e, f $$ that need to be determined. The equation is:

$$
\int_{0}^{\frac{3}{2}} x^{2} dx + \int_{\frac{3}{2}}^{3} \left(x^{2} + 3x^{3}\right) dx + \int_{3}^{4} \left(3x^{3} - 1\right) dx
$$

The goal is to find the values of $$ a, b, c, d, e, f $$ such that this equation holds true. Additionally, there's a second part of the problem that involves calculating another integral expression:

$$
\int_{0}^{3} x^{2} dx + \int_{3}^{1} 3x^{3} dx - \int_{2}^{d} 1 dx = \square x^{3} dx - \int_{e}^{f} 1 dx
$$

Let's tackle the first part first.

**First Part: Determining Constants $$ a, b, c, d, e, f $$**

The equation provided is a sum of three definite integrals. To find the constants, I need to evaluate each integral and set them equal to the given expression. However, the problem statement doesn't specify what the equation should equal. It seems like the equation is set to be correct, but without a target value or another equation to compare it to, it's challenging to determine the constants directly.

Perhaps there's a missing part of the problem or a specific value that the equation should equal. Without additional information, I can't proceed to find the exact values of the constants. Maybe the constants are placeholders for variables that need to be determined based on certain conditions or constraints not provided here.

Alternatively, if the equation is intended to be an identity, meaning the left side equals the right side for some values of the constants, I would need to set up equations based on the equality of the integrals. For example, equating the coefficients of like terms or ensuring that the integrals evaluate to the same numerical value.

But without knowing what the equation should equal or any additional constraints, I can't determine the specific values of $$ a, b, c, d, e, f $$. It's possible that the problem is incomplete or requires more information to be solvable.

**Second Part: Calculating the Integral Expression**

Moving on to the second part of the problem:

$$
\int_{0}^{3} x^{2} dx + \int_{3}^{1} 3x^{3} dx - \int_{2}^{d} 1 dx = \square x^{3} dx - \int_{e}^{f} 1 dx
$$

Let's evaluate each integral step by step.

1. **First Integral:**
$$
\int_{0}^{3} x^{2} dx = \left[ \frac{x^{3}}{3} \right]_{0}^{3} = \frac{27}{3} - 0 = 9
$$

2. **Second Integral:**
$$
\int_{3}^{1} 3x^{3} dx = 3 \int_{3}^{1} x^{3} dx = 3 \left[ \frac{x^{4}}{4} \right]_{3}^{1} = 3 \left( \frac{1}{4} - \frac{81}{4} \right) = 3 \left( -\frac{80}{4} \right) = -60
$$

3. **Third Integral:**
$$
\int_{2}^{d} 1 dx = [x]_{2}^{d} = d - 2
$$

Putting it all together:
$$
9 - 60 - (d - 2) = -51 - d
$$

So, the expression simplifies to:
$$
-51 - d
$$

But the problem states:
$$
-51 - d = \square x^{3} dx - \int_{e}^{f} 1 dx
$$

This implies that:
$$
\square x^{3} dx = -51 - d + \int_{e}^{f} 1 dx
$$

However, without knowing the values of $$ e $$ and $$ f $$, or additional information about the constants, I can't determine the exact value of $$ \square $$. It seems like there's missing information in this part of the problem as well.

**Conclusion**

In summary, to determine the values of the constants $$ a, b, c, d, e, f $$ in the first part of the problem, more information is needed, such as the target value or additional equations to which the integrals should equal. Similarly, in the second part, without knowing the values of $$ e $$ and $$ f $$, or the specific form of $$ \square $$, I can't provide a definitive answer. It appears that the problem is incomplete or requires additional details to be fully solvable.

Cannot determine the values of the constants $$ a, b, c, d, e, f $$ with the given information.
