limit as x approaches pi/2 of 7cos(-5x)sec(-7x)

解

x \to \frac{π}{2} lim (7 cos (- 5 x) sec (- 7 x))

解

- 5

解答ステップ

x \to \frac{π}{2} lim (7 cos (- 5 x) sec (- 7 x))

x \to a - lim f (x) = x \to a + lim f (x) = L

の場合は

x \to a lim f (x) = L

x \to \frac{π}{2} - lim (7 cos (- 5 x) sec (- 7 x)) = - 5

x \to \frac{π}{2} + lim (7 cos (- 5 x) sec (- 7 x)) = - 5

= - 5
