Did you know that the sine double angle formula is a gem in trigonometry? It states that \( \sin(2A) = 2 \sin(A) \cos(A) \). This little formula can simplify many problems involving sine functions, making it easier to analyze oscillations or waves in physics! Furthermore, this formula isn’t just for textbooks; it has real-world applications, especially in engineering and physics! For instance, it's crucial for analyzing periodic functions, such as sound waves and light, where understanding the relationship between sine and cosine can lead to better acoustic designs or optics developments. So, the next time you hear a cool sound or see a beam of light, think about that nifty sine double angle formula!

1. Lulama was asked to evaluate the following expression without the use of a calculator: \( \sin \left(180^{\circ}-135^{\circ}\right) \). She answered as follows: \[ \begin{array}{l} \operatorname{Sin}\left(180^{\circ}-135^{\circ}\right)=\sin 180^{\circ}-\sin 135^{\circ} \\ =0-\sin \left(180^{\circ}-45^{\circ}\right) \text { (step 1) } \\ \text { (step2) } \\ = \text { (step 3) } \\ =-\frac{\sin 45^{\circ}}{2} \text { (step 4) }\end{array} \] \( \begin{array}{ll}\text { 1.1. What law or property did Lulama use to write step 1? } & \text { (1) }\end{array} \) 1.2 Do you think Lulama is correct? Motivate your answer?
