The image contains a mathematical problem involving integrals and some constraints. Here is what I can discern from the image:

1. **Given parameters**:  
   \( a = 6 \), \( b = -2 \).

2. **The main problem**:
   You are tasked to prove:
   \[
   \int_0^1 f(x) \, dx \leq \frac{\pi}{4}.
   \]

3. **The function** \( f(x) \) is described to be continuous on the interval \([0,1]\), and it satisfies the inequality:
   \[
   x f(y) + y f(x) \leq 1 \quad \text{for all} \quad x, y \in [0, 1].
   \]

---

This problem seems to involve both integral calculus and inequalities. The aim is to prove that the integral of \( f(x) \) over the interval \([0,1]\) is less than or equal to \( \frac{\pi}{4} \), given that \( f(x) \) satisfies the stated condition.

Would you like a step-by-step detailed solution to this problem, or do you have any specific parts you need clarification on?

Here are five possible related questions you might consider:
1. What is the significance of the inequality \( x f(y) + y f(x) \leq 1 \) in the context of this problem?
2. How does the inequality help in bounding the integral of \( f(x) \)?
3. What methods could be used to prove this inequality holds?
4. Is it possible to find an explicit form for \( f(x) \) or just a bound?
5. How does the value \( \frac{\pi}{4} \) relate to this inequality and the integral?

**Tip**: Sometimes geometric interpretations or symmetry properties of the function \( f(x) \) help in solving such problems involving integrals and inequalities.

求证：∫_0^1 f(x) dx ≤ π/4, where f is continuous on [0, 1] and satisfies the inequality x f(y) + y f(x) ≤ 1 for all x, y ∈ [0, 1].

This problem involves proving that the integral of a continuous function f(x) over the interval [0,1] is less than or equal to π/4, under the condition that x f(y) + y f(x) ≤ 1 for all x, y in [0,1]. Learn about key concepts in integral calculus and inequalities.
