erweitern (sin(x)-1)(cos(x)+1)

Lösung

erweitern

(sin (x) - 1) (cos (x) + 1)

cos (x) sin (x) + sin (x) - cos (x) - 1

Schritte zur Lösung

(sin (x) - 1) (cos (x) + 1)

Apply FOIL method

(sin (x) - 1) (cos (x) + 1) : cos (x) sin (x) + sin (x) - cos (x) - 1

= cos (x) sin (x) + sin (x) - cos (x) - 1

s im pl i f y \frac{( 1 - 3 ) ^{4}}{16} + 3 - 1

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

s im pl i f y \frac{3}{13} \cdot (7 - 3) + \frac{4}{13} (0.25 \cdot 3) + \frac{14}{13} (- 3)

e x p an d \frac{1 - 3 i}{1 + 3 i}

e x p an d \frac{1}{x + 4}
