vereinfachen (cos(t)+sin(t))*(-sin(t))

Lösung

vereinfachen

(cos (t) + sin (t)) \cdot (- sin (t))

- sin (t) (cos (t) + sin (t))

Schritte zur Lösung

(cos (t) + sin (t)) (- sin (t))

Apply rule:

a (- b) = - ab

(cos (t) + sin (t)) (- sin (t)) = - (cos (t) + sin (t)) sin (t)

= - (cos (t) + sin (t)) sin (t)

= - sin (t) (cos (t) + sin (t))

e x p an d (s + 1) (s + 3) + \frac{1}{s} + \frac{x}{s} + \frac{y}{s} (s + 1)

e x p an d (y^{'} (x) + y cot (x)) sin (x)

e x p an d (2 y - x + 3) d x + 2 d y

e x p an d (13 a + 8 b = 2,) (11 a + 4 b = 1)

e x p an d \frac{1}{9} (e^{3 t} \cdot 3 t - e^{3 t})
