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

Lösung

erweitern

(1 - cot (x)) (1 + cos (x))

1 + cos (x) - cot (x) - cos (x) cot (x)

Schritte zur Lösung

(1 - cot (x)) (1 + cos (x))

Apply FOIL method

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

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

e x p an d (\frac{80 x}{20} = \frac{x z}{30} + \frac{x y}{30}) (20) (30)

s im pl i f y (x - 6) (x - 2)

e x p an d 5 (3 - 10)

e x p an d a (1, - 1) b (- 6, 7)

e x p an d \frac{3 x ( x - 2 ) - 16 x y}{4 y - 3 x ^{2}}
