Value of cos(2x over 3)

Answer 1

To find the value of $\cos \left(\frac{2x}{3}\right)$, you'll need a specific value for $x$. Without a numeric input for $x$, I can’t provide a specific numerical value for $\cos \left(\frac{2x}{3}\right)$.

If you have a particular value for $x$, you can plug that value into the expression to compute $\cos \left(\frac{2x}{3}\right)$. Alternatively, if you're looking for a formula involving cosine or ways to calculate it in general, please let me know!
