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

Lösung

erweitern

(cos (x) + k) (k - sin (x))

k cos (x) - cos (x) sin (x) + k^{2} - k sin (x)

Schritte zur Lösung

(cos (x) + k) (k - sin (x))

Apply FOIL method

(cos (x) + k) (k - sin (x)) : k cos (x) - cos (x) sin (x) + k^{2} - k sin (x)

= k cos (x) - cos (x) sin (x) + k^{2} - k sin (x)

s im pl i f y x (x - 3)^{2}

s im pl i f y (x^{\frac{3}{2}} - 4 x) (x^{4} - \frac{3}{x ^{2}} + 2)

s im pl i f y (3 x - 2) \times (3 x + 2)

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

e x p an d (4 x + \frac{1}{k x})^{7}
