NCERT · Class 11 · Mathematics · Trigonometric FunctionsWhat is the value of $\tan\left(\frac{19\pi}{3}\right)$?
Step-by-Step Solution
We can write $\frac{19\pi}{3} = 6\pi + \frac{\pi}{3} = 3(2\pi) + \frac{\pi}{3}$. Since $\tan(2n\pi + x) = \tan x$, we have $\tan\left(6\pi + \frac{\pi}{3}\right) = \tan\left(\frac{\pi}{3}\right) = \sqrt{3}$.
