Why is my approach for showing $r^2 \\frac{\\theta}{2}$ equals the area . . .
To convert $\frac{\theta}{360º}$ into radians, $\theta$ is a variable and can be either in degrees or radians: $\theta = 2\pi$ or $\theta = 360º$ both work However, if $\theta$ is in radians, $360º$ should also be in radians, or otherwise you have to multiply by some conversion factor
R Squared | Coefficient of Determination | GeeksforGeeks
R-squared, also known as the coefficient of determination, is a statistical measure that represents the proportion of the variance for a dependent variable that's explained by one or more independent variables in a regression model In simpler terms, it shows how well the data fit a regression line or curve
frac{pi}{2} - Symbolab

Coefficient of determination - Wikipedia
In statistics, the coefficient of determination, denoted R 2 or r 2 and pronounced "R squared", is the proportion of the variation in the dependent variable that is predictable from the independent variable(s)
Coefficient of Determination (R²) | Calculation Interpretation - Scribbr
You can choose between two formulas to calculate the coefficient of determination (R ²) of a simple linear regression The first formula is specific to simple linear regressions, and the second formula can be used to calculate the R ² of many types of statistical models Where r = Pearson correlation coefficient
三角函数公式 - 知乎 - 知乎专栏
假设 f(x) 是一个三角函数，我们需要化简 f\left(k\cdot \frac{\pi}{2}\pm\theta\right) ，其中 \theta 为锐角： 0\leq \theta < \frac{\pi}{2} ， k 为整数。首先，我们要确认这个角 \left(k\cdot \frac{\pi}{2} \pm\theta\right) 的终边在第几象限。接着
