vereinfachen (1-tan(x))(cos(2x))

Lösung

vereinfachen

(1 - tan (x)) (cos (2 x))

(1 - tan (x)) cos (2 x)

Schritte zur Lösung

(1 - tan (x)) (cos (2 x))

Apply rule:

(a) = a

(cos (2 x)) = cos (2 x)

= (1 - tan (x)) cos (2 x)

e x p an d (tan (2 x) + tan (x)) (cos (3 x) + cos (x))

e x p an d \frac{3 x + 5}{( x + 1 ) ( x ^{2} + 3 x + 2 )}

s im pl i f y (P + \frac{n ^{2} a}{v ^{2}}) (v - nb)

e x p an d \frac{5}{( x + 4 ) ^{2}}

e x p an d 2 (6 - \frac{4}{3}) π
