What is the limit as x approaches π/2 of cos(3x)tan(x)? Stuck on this particular part: http://i.gyazo.com/bb86872077923d945436f0aca6585ec7.png

Answer 1

can you help me with a math problem.. it is around the top

Answer 2

\[\lim_{x \rightarrow \frac{\pi}{2}} \cos(3x)\tan(x) \]
\[\lim_{x \rightarrow \frac{\pi}{2}} \frac{\cos(3x)}{\cot(x)}=\lim_{x \rightarrow \frac{\pi}{2}}\frac{-3\sin(3x)}{-\csc^2(x)} \\ \]
try this
maybe this helps

Answer 3

That's exactly what I needed, thank you very much freckles!
