limit as x approaches 0-of 1/(cos(x))

x \to 0 - lim (\frac{1}{cos ( x )})

1

Solution steps

x \to 0 - lim (\frac{1}{cos ( x )})

Plug in the value

x = 0

= \frac{1}{cos ( 0 )}

Simplify

\frac{1}{cos ( 0 )} : 1

= 1

x \to - 1 + lim (\frac{ln ( x + 1 )}{x})

x \to - 2 lim (\frac{x ^{2} - x}{x + 2})

x \to 3 + lim (\frac{7 x - 5}{x - 3})

x \to 4 lim (\frac{3 x - 1}{x - 4})

x \to 2 lim (3 x^{2} + 5)
