expand (1+e^x)(1-e^x)

expand

(1 + e^{x}) (1 - e^{x})

1 - e^{2 x}

Solution steps

(1 + e^{x}) (1 - e^{x})

Apply Difference of Two Squares Formula:

(a + b) (a - b) = a^{2} - b^{2}

a = 1, b = e^{x}

= 1^{2} - (e^{x})^{2}

Simplify

1^{2} - (e^{x})^{2} : 1 - e^{2 x}

= 1 - e^{2 x}

25 (1 + cos (θ))

A (4, 1) y B (- 2, - 2)

(t^{2} + 1) y^{'} (t) + t y - 2 t

(\frac{3}{2}, - 3) y (\frac{1}{2}, \frac{( - 3 )}{4})

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