limit as x approaches pi/2 of 1/(tan(x))

x \to \frac{π}{2} lim (\frac{1}{tan ( x )})

0

Solution steps

x \to \frac{π}{2} lim (\frac{1}{tan ( x )})

x \to a lim [\frac{f ( x )}{g ( x )}] = \frac{lim _{x \to a} f ( x )}{lim _{x \to a} g ( x )}, x \to a lim g (x) \neq = 0

With the exception of indeterminate form

= \frac{lim _{x \to \frac{π}{2}} ( 1 )}{lim _{x \to \frac{π}{2}} ( tan ( x ) )}

x \to \frac{π}{2} lim (1) = 1

x \to \frac{π}{2} lim (tan (x)) = - \infty

= \frac{1}{- \infty}

Apply Infinity Property:

\frac{c}{- \infty} = 0

= 0
