Question

Find tan^-1 infinity/4.

Answer 1

@Hero

Answer 2

is it
\[\lim_{x\to \infty}\frac{\tan^{-1}(x)}{4}\]?

Answer 3

No, tangent inverse of infinity/4.

Answer 4

there is no such number as \(\frac{\infty}{4}\)

Answer 5

as \(x\to \infty\) you have \(\tan^{-1}(x)\to \frac{\pi}{2}\)
maybe that helps, not sure

Answer 6

So the answer is pi/2 since that's the domain of tangent inverse?

Answer 7

Probably.
