erweitern (3+j^3)*(1+jsqrt(3))

Lösung

erweitern

(3 + j^{3}) \cdot (1 + j 3)

3 + 33 j + j^{3} + 3 j^{4}

Schritte zur Lösung

(3 + j^{3}) (1 + j 3)

Apply FOIL method

(3 + j^{3}) (1 + j 3) : 3 + 33 j + j^{3} + 3 j^{4}

= 3 + 33 j + j^{3} + 3 j^{4}

e x p an d (x^{2} + 2) cos (3 x + 4)

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

e x p an d x^{6} + (y - 2)^{6}

e x p an d \frac{36 ( x ^{2} - 42 x + 432 )}{π} - 1623
