Here are the essential concepts you must grasp in order to answer the question correctly.
Multiple Angle Formulas
Multiple angle formulas are trigonometric identities that express trigonometric functions of multiple angles in terms of functions of single angles. For example, cos(4x) can be rewritten using the double angle formula, which is essential for simplifying and solving equations involving angles that are multiples of a basic angle.

Interval Notation
Interval notation is a mathematical notation used to represent a range of values. In this context, the interval [0, 2Ο) indicates that solutions must be found within the range starting from 0 up to, but not including, 2Ο. Understanding this notation is crucial for determining valid solutions to the trigonometric equation.
