expand e^y*(1-e^{-2y})

expand

e^{y} \cdot (1 - e^{- 2 y})

e^{y} - e^{- y}

Solution steps

e^{y} (1 - e^{- 2 y})

Apply the distributive law:

a (b - c) = ab - a c

a = e^{y}, b = 1, c = e^{- 2 y}

= e^{y} \cdot 1 - e^{y} e^{- 2 y}

= 1 \cdot e^{y} - e^{y} e^{- 2 y}

Simplify

1 \cdot e^{y} - e^{y} e^{- 2 y} : e^{y} - e^{- y}

= e^{y} - e^{- y}

(a - b x)^{2}

(6 x + 7 - 4)^{2}

(3) d i rec t r i z (y - 7 = 0)

(\frac{1}{2} m^{x} - 6 n^{y})^{2}

(x^{2} + \frac{5}{49}) (x^{2} - 4 x + 4)
