limit as x approaches 0 of 1/(cos^2(x))

x \to 0 lim (\frac{1}{cos ^{2} ( x )})

1

Solution steps

x \to 0 lim (\frac{1}{cos ^{2} ( x )})

Plug in the value

x = 0

= \frac{1}{cos ^{2} ( 0 )}

Simplify

\frac{1}{cos ^{2} ( 0 )} : 1

= 1

b \to 1 - lim (- \frac{1}{b - 1} - 1)

x \to 0 lim (\frac{3}{4} x + 1)

x \to \infty lim (1 - 4 x)

x \to 1 + lim (3 x + 2)

x \to 0 lim (\frac{tan ( 2 x )}{6 x})
