erweitern cot(4x)(sin(x)+sin(4x)+sin(7x))

Lösung

erweitern

cot (4 x) (sin (x) + sin (4 x) + sin (7 x))

cot (4 x) sin (x) + cot (4 x) sin (4 x) + cot (4 x) sin (7 x)

Schritte zur Lösung

cot (4 x) (sin (x) + sin (4 x) + sin (7 x))

Wende das Distributivgesetz an:

m (a + b + c) = ma + mb + m c

cot (4 x) (sin (x) + sin (4 x) + sin (7 x)) = cot (4 x) sin (x) + cot (4 x) sin (4 x) + cot (4 x) sin (7 x)

= cot (4 x) sin (x) + cot (4 x) sin (4 x) + cot (4 x) sin (7 x)

e x p an d e^{\frac{b}{( m + b y ) ( - b y - m )}}

e x p an d \frac{x ^{3} + 2 x ^{2} + x + 4}{( x + 1 ) ^{2}}

e x p an d (e^{2} - \frac{1}{e}) 9

e x p an d - \frac{x ^{2}}{3 ( x - 1 ) ( x + 1 ) ( x ^{2} - 2 )}
