expand 2pi*(1-1/(e^2))

expand

2 π \cdot (1 - \frac{1}{e ^{2}})

2 π - \frac{2 π}{e ^{2}}

Solution steps

2 π (1 - \frac{1}{e ^{2}})

Apply the distributive law:

a (b - c) = ab - a c

a = 2 π, b = 1, c = \frac{1}{e ^{2}}

= 2 π 1 - 2 π \frac{1}{e ^{2}}

= 2 \cdot 1 π - 2 π \frac{1}{e ^{2}}

Simplify

2 \cdot 1 π - 2 π \frac{1}{e ^{2}} : 2 π - \frac{2 π}{e ^{2}}

= 2 π - \frac{2 π}{e ^{2}}

\frac{2}{x ( x + 1 ) ^{2}}

\frac{1 ^{2}}{S ( S ^{2} + 1 ^{2} )}

A (6, 0) B (0, - 6)

\frac{1}{( s - 1 ) ( s + 2 )}

(c x + z)^{2} + x^{2} s^{2}
