Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Coterminal Angles
Coterminal angles are angles that share the same terminal side when drawn in standard position. To find coterminal angles, you can add or subtract multiples of 360° (for degrees) or 2π (for radians) to the given angle. For example, 135° and 495° are coterminal because 495° = 135° + 360°.

Coterminal Angles
Integer Representation
In the context of generating coterminal angles, 'n' represents any integer, which allows for the creation of an infinite set of angles. By substituting different integer values into the expression for coterminal angles, you can generate all possible angles that are coterminal with the original angle. This flexibility is crucial for understanding the periodic nature of trigonometric functions.

Introduction to Common Polar Equations
Angle Measurement
Angles can be measured in degrees or radians, and understanding this distinction is essential when working with trigonometric concepts. In this case, the angle is given in degrees (135°), and when generating coterminal angles, it is important to consistently use the same unit of measurement. Converting between degrees and radians may be necessary depending on the context of the problem.
