# Question Solved1 AnswerThis question is based on Section $$1.3$$. (A) Draw the graphs of $$y=\sin x$$ and $$y=\cos x$$, separately, and restrict the graphs to the period $$[0,2 \pi]$$. You may copy the graphs from the textbook. [2 marks]. (B) Explain how a Double-Angle Identity (found in the textbook) and the graphs of sine and cosine can help you solve the equation $$This question is based on Section \( 1.3$$.
