Question
### Understanding Trigonometric Identities The following are some fundamental relationships in trigonometry involving the sine and cosine functions. This content is designed to test your understanding of these identities by determining whether each provided equation is true or false. #### Diagram Description The diagram shows a unit circle with a radius centered at the origin \( C \) on the coordinate system. An angle \( \theta \) is marked counterclockwise from the positive \( x \)-axis. A point \((x, y)\) on the circumference of the circle corresponds to the angle \( \theta \). #### Equations and True/False Table Below is a set of trigonometric equations. Your task is to determine whether each equation is true or false: 1. \( x = \sin(\theta) \) 2. \( x = \cos(2\pi - \theta) \) 3. \( y = \sin(\pi + \theta) \) 4. \( \cos(\theta) = \cos(2\pi - \theta) \) 5. \( -\sin(\theta) = \sin(\pi + \theta) \) **Indicate your answers by selecting either True or False for each equation.** | Equation | True | False | |---------------------------------------|------|-------| | \( x = \sin(\theta) \) | ( ) | ( ) | | \( x = \cos(2\pi - \theta) \) | ( ) | ( ) | | \( y = \sin(\pi + \theta) \) | ( ) | ( ) | | \( \cos(\theta) = \cos(2\pi - \theta) \) | ( ) | ( ) | | \( -\sin(\theta) = \sin(\pi + \theta) \) | ( ) | ( ) | ### Explanation of Trigonometric Relationships 1. **\( x = \sin(\theta) \)**: Typically, for a unit circle, the \( x \)-coordinate is expressed as \( \cos(\theta) \). 2. **\( x = \cos(2\pi - \theta) \)**: Using the periodic property of cosine, \(\cos(2\pi - \theta) = \cos(\theta)\), which implies this equation is generally true. 3. **\( y
