limit as x approaches 0 of a^x+a^{-x}

x \to 0 lim (a^{x} + a^{- x})

2

Solution steps

x \to 0 lim (a^{x} + a^{- x})

Plug in the value

x = 0

= a^{0} + a^{- 0}

Simplify

= 2

\int (3 x + 4)^{6} d x

y^{^{'}} + e^{x} y = 19 e^{x}

\frac{\partial}{\partial w} ((y - w (x + x^{2}))^{2})

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

\int \frac{( x ^{3} )}{x ^{2} + 36} d x
