Find the intervals where the function is increasing or decreasing . Use a sign chart to organize your analysis. #4 ### Mathematical Function Analysis**Function:** \( f(x) = \sin x + \cos x \)**Domain:** \( (0, 2\pi) \)---This content appears to focus on the trigonometric function \( f(x) = \sin x + \cos x \) over the interval \( (0, 2\pi) \). ### Exploration of the Function1. **Understanding the Graph and Behavior:** - The function is composed of the sine and cosine functions, which are periodic with a period of \( 2\pi \). - Analyzing this on the interval \( (0, 2\pi) \), we expect the function to exhibit wave-like characteristics due to the nature of the sine and cosine components.2. **Property Analysis:** - **Amplitude and Phase Shift:** Both sine and cosine have an amplitude of 1. The resulting function \( \sin x + \cos x \) can be rewritten using the amplitude and phase shift formula: \[ f(x) = \sqrt{2}\sin(x + \frac{\pi}{4}) \] Thus, the amplitude is \(\sqrt{2}\), and there is a phase shift of \(\frac{\pi}{4}\). - **Zeros and Critical Points:** Solving \( \sin x + \cos x = 0 \) within this interval will provide the zeros, and taking the derivative to find critical points will show where the function reaches maximum or minimum values.3. **Practical Applications:** - Understanding oscillations in wave motion. - Analyzing alternating current electricity outcomes.---This content can be used on an educational website to teach students about trigonometric functions, their transformations, and their implications in real-world scenarios.
