If \(\theta=0^\circ\), what is the value of \(\sin \theta\)?

Answer and explanation

Correct answer: 0

For the standard angle, \(\sin 0^\circ=0\). On the unit circle, the point corresponding to \(0^\circ\) is \((1,0)\), and sine is the \(y\)-coordinate of that point. Therefore, the correct value is 0. Since \(\sin 90^\circ=1\), 1 is not correct here. Exam tip: Remember the sine values from \(0^\circ\) to \(90^\circ\) in the order \(0,\frac{1}{2},\frac{1}{\sqrt{2}},\frac{\sqrt{3}}{2},1\).
