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

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 \cdot 0 )}

Simplify

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

= 1

\int_{0}^{L} 0 d x

x \to 3 lim (\frac{x ^{2} - 1}{x + 1})

(2 + x^{5})^{\frac{2}{3}}

\frac{d y}{d x} = \frac{x}{2 y ^{2}}, y (0) = 1

y^{^{'}} - e^{9 x + y} = 0
