Select your answer \( \quad \) (4 out of 25) \( -\frac{\pi}{2} \) \( -\frac{\pi}{3} \) \( -\frac{2 \pi}{3} \) \( -\frac{3 \pi}{4} \) Convert \( -90^{\circ} \) into radians. ?

Did you know that the conversion from degrees to radians is as simple as multiplying by \(\frac{\pi}{180}\)? So, to convert \(-90^{\circ}\) to radians, you simply calculate \(-90 \times \frac{\pi}{180}\), which simplifies to \(-\frac{\pi}{2}\). Voilà! This conversion is essential in various fields such as engineering and physics where angular measurements often need to be in radians for trigonometric function calculations. Understanding how to switch between these units can save you a lot of confusion and time when working with rotational dynamics or wave functions!
