What is the value of (\cos 60^\circ)?
Advertisement
Answer and explanation
Correct answer: \(\frac{1}{2}\)
From the standard trigonometric values, \(\cos 60^\circ=\frac{1}{2}\), so option B is correct. \(\frac{\sqrt{3}}{2}\) is the value of \(\cos 30^\circ\), not \(\cos 60^\circ\). Exam tip: Memorise the standard values for \(30^\circ\), \(45^\circ\), and \(60^\circ\).
