∻Solution by Steps∻ ‖ step 1 ⋮ Identify the angle for which we need to find the cosine value. ‖ ‖ step 2 ⋮ Use the unit circle or trigonometric identities to find the cosine of the given angle. ‖ ‖ step 3 ⋮ Recognize that $\cos\left(\frac{\pi}{3}\right)$ corresponds to the cosine of 60 degrees. ‖ ‖ step 4 ⋮ Recall that $\cos(60^\circ) = \cos\left(\frac{\pi}{3}\right) = \frac{1}{2}$. ‖ ∻[1] Answer∻ ⚹ $\cos\left(\frac{\pi}{3}\right) = \frac{1}{2}$ ⚹ ∻Key Concept∻ ⚹Cosine of an angle in a right triangle⚹ ∻Explanation∻ ⚹The cosine of an angle in a right triangle is the ratio of the adjacent side to the hypotenuse. For angles of common measures, such as $\frac{\pi}{3}$ radians (60 degrees), the cosine value can be found using trigonometric identities or the unit circle. In this case, $\cos\left(\frac{\pi}{3}\right) = \frac{1}{2}$.⚹◊What is the cosine value of $\frac{\pi}{3}$?⍭ Generate me a similar question◊
