Question

Maybe this will be easier to answer than my other post without much context, there is two triangles as shown at the top of the image, one with side length 3 and one with 6, P is the point where the triangles meet. You are asked to maximize theta (the angle between the two triangles) by moving P. I have done the derivative of theta but I am not sure what to set it equal to. 0 doesn't seem to make sense and it can only be between 0 and pi because the max angle if no triangles were there would be 180 degrees or pi so please help. This should give a lot more context than my other version of this question.

The text presents a mathematical derivation and analysis involving angles and trigonometric functions. Here's a detailed transcription and explanation:

---

**Diagrams and Equations:**

1. **Diagram of Triangle:**
- A triangle labeled with sides 3, 6, and $ b - x $.
- Points labeled: $ B $, $ P $, and possibly $ A $.
- Angles $ \alpha $ and $ \beta $ are marked at two vertices.

2. **Equation:**
\[
\Theta = \pi - \alpha - \beta
\]

3. **Trigonometric Expressions:**
- $\tan(\alpha) = \frac{3}{b-x} \Rightarrow \alpha = \tan^{-1}\left(\frac{3}{b-x}\right)$
- $\tan(\beta) = \frac{6}{x} \Rightarrow \beta = \tan^{-1}\left(\frac{6}{x}\right)$

4. **Expression for $\Theta(x)$:**
\[
\Theta(x) = \pi - \alpha - \beta = \pi - \tan^{-1}\left(\frac{3}{b-x}\right) - \tan^{-1}\left(\frac{6}{x}\right)
\]

5. **Further Derivation:**
- $ a(x) = \frac{1}{\tan x} $, therefore,
\[
\Theta(x) = -\frac{1}{1+\left(\frac{3}{(6-x)^2}\right)} + \frac{1}{1+\left(\frac{6^2}{x^2}\right)} \times \frac{6}{x}
\]

6. **Algebraic Manipulation:**
- $ (6-x) = (x-6)^2 $
- Expanding and simplifying expressions involving $(6-x)^2$ and fractions.

7. **Derivative Calculation:**
\[
\frac{d\Theta}{dx} = \frac{3}{(6-x)^2 + 9} + \frac{6}{x^2 + 36}
\]

---

**Explanation of Concepts:**

- The expressions involve basic trigonometric identities and inverse trigonometric functions, mainly focusing on manipulating the tangent function
