limit as x approaches pi/2+of 9/x sec(x)

x \to \frac{π}{2} + lim (\frac{9}{x} sec (x))

- \infty

Solution steps

x \to \frac{π}{2} + lim (\frac{9}{x} sec (x))

x \to a lim [c \cdot f (x)] = c \cdot x \to a lim f (x)

= 9 \cdot x \to \frac{π}{2} + lim (\frac{1}{x} sec (x))

x \to a lim [f (x) \cdot g (x)] = x \to a lim f (x) \cdot x \to a lim g (x)

With the exception of indeterminate form

= 9 \cdot x \to \frac{π}{2} + lim (\frac{1}{x}) \cdot x \to \frac{π}{2} + lim (sec (x))

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

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

= 9 \cdot \frac{2}{π} (- \infty)

Apply Infinity Property:

c \cdot (- \infty) = - \infty

= - \infty
