erweitern 2-(sin(x)+cos(y))2-(cos(x)+sin(y))2

Lösung

erweitern

2 - (sin (x) + cos (y)) 2 - (cos (x) + sin (y)) 2

2 - 2 sin (x) - 2 cos (y) - 2 cos (x) - 2 sin (y)

Schritte zur Lösung

2 - (sin (x) + cos (y)) \cdot 2 - (cos (x) + sin (y)) \cdot 2

= 2 - 2 (sin (x) + cos (y)) - 2 (cos (x) + sin (y))

Schreibe

- 2 (sin (x) + cos (y))

um:

- 2 sin (x) - 2 cos (y)

= 2 - 2 sin (x) - 2 cos (y) - 2 (cos (x) + sin (y))

Schreibe

- 2 (cos (x) + sin (y))

um:

- 2 cos (x) - 2 sin (y)

= 2 - 2 sin (x) - 2 cos (y) - 2 cos (x) - 2 sin (y)
