limit as z approaches 2pii of e^z-e^{-z}

z \to 2 πi lim (e^{z} - e^{- z})

e^{2 πi} - e^{- 2 πi}

Solution steps

z \to 2 πi lim (e^{z} - e^{- z})

Plug in the value

z = 2 πi

= e^{2 πi} - e^{- 2 πi}

\int_{4}^{6} \frac{1}{t ^{2} - 9} d t

\frac{d}{d x} (\frac{1}{1 + y ^{2}} + cos (x) - 2 x y)

4 e^{x - 3}

\frac{d}{d y} (x^{2} + y^{2} + z^{2})

x \cdot \frac{d y}{d x} + y = 4 x + 1
