Step 2: Understanding Periodic Functions
When solving trigonometric equations, adding $$2\pi k$$ (where $$k$$ is any integer) is crucial for finding the general solution of periodic trigonometric functions.
This accounts for the repeating nature of sine and cosine functions.
Final Answer
Adding 2\pi k accounts for all solutions by adding integer multiples of the period, ensuring a comprehensive representation of the trigonometric function's periodic nature. Key Insight: The 2\pi k term allows us to express the infinite set of solutions that satisfy a trigonometric equation by systematically generating angles that produce the same trigonometric value.
