(e^{j t})^{2}

e^{2 j t}

求解步骤

(e^{j t})^{2}

使用指数法则:

(a^{b})^{c} = a^{b c}

= e^{j t \cdot 2}

e x p an d \frac{( a ^{2} + 9 ) ( a ^{2} - 3 ) 3}{4 a ^{2}}

e x p an d \frac{1}{s ( s ^{2} + A ^{2} )}

e x p an d 4 + f (2 t - 7) H (t - 2)

e x p an d \frac{2}{3} n - \frac{1}{4}

e x p an d \frac{x ( x - 1 )}{( x - 2 ) ( x - 4 )}
