(t e^{t y} cos (2 t) - 3) d t

e^{t y} t cos (2 t) d t - 3 d t

Schritte zur Lösung

(t e^{t y} cos (2 t) - 3) d t

= (e^{t y} t cos (2 t) - 3) d t

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = d t, b = t e^{t y} cos (2 t), c = 3

= d tt e^{t y} cos (2 t) - d t \cdot 3

= e^{t y} t cos (2 t) d t - 3 d t

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

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

e x p an d (0.685 = 805 x + 40 y) 60

e x p an d \frac{( x + 1 ) ( 2 x + 1 )}{10 x ( x - 3 )}

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