Understanding the Problem
When dealing with trigonometric functions, it's essential to understand the relationship between the angle, the unit circle, and the coordinates of the point where the terminal side intersects the circle. In this problem, we are given the coordinates {\left(\frac{11}{61}, \frac{60}{61}\right)$}$ and asked to find the cosecant of the angle {\theta$}$.
The Unit Circle and Trigonometric Functions
The unit circle is a circle with a radius of 1 centered at the origin of the coordinate plane. The terminal side of an angle in standard position intersects the unit circle at a point, and the coordinates of this point are used to define the trigonometric functions. The cosecant function, denoted as {\csc (\theta)$}$, is the reciprocal of the sine function, and it can be calculated using the coordinates of the point where the terminal side intersects the unit circle.
Calculating the Cosecant Function
To calculate the cosecant function, we need to find the sine of the angle {\theta$}$ and then take its reciprocal. The sine function can be calculated using the coordinates of the point where the terminal side intersects the unit circle. In this case, the coordinates are {\left(\frac{11}{61}, \frac{60}{61}\right)$}$. The sine function is defined as the ratio of the y-coordinate to the radius of the unit circle, which is 1.
Finding the Sine of the Angle
Using the coordinates {\left(\frac{11}{61}, \frac{60}{61}\right)$}$, we can calculate the sine of the angle {\theta$}$ as follows:
Finding the Cosecant of the Angle
Now that we have the sine of the angle, we can calculate the cosecant function by taking its reciprocal:

In this problem, we were given the coordinates {\left(\frac{11}{61}, \frac{60}{61}\right)$}$ and asked to find the cosecant of the angle {\theta$}$. We used the unit circle and the definition of the sine function to calculate the sine of the angle, and then took its reciprocal to find the cosecant function. The final answer is {\frac{61}{60}$}$.
