simplify (1-0.8e^{-ix})^2

simplify

(1 - 0.8 e^{- i x})^{2}

(1 - 0.8 (cos (x) - i sin (x)))^{2}

Solution steps

(1 - 0.8 e^{- i x})^{2}

e^{- i x} = cos (x) - i sin (x)

= (1 - 0.8 (cos (x) - i sin (x)))^{2}

2 (2 e^{\frac{x}{2}} + C)

\frac{2}{( 1 + e ^{- 8 (x - 0.7)} )} - 1

4 sin (2 x - \frac{π}{2})

\frac{x}{s ( T s + 1 )}

\frac{r ^{2} ( r + 3 )}{r - 3}
