erweitern 4(3cos(t)+1)-(3sin(t)+3)^2sin(3cos(t)+1)

Lösung

erweitern

4 (3 cos (t) + 1) - (3 sin (t) + 3)^{2} sin (3 cos (t) + 1)

12 cos (t) + 4 - 9 sin^{2} (t) sin (3 cos (t) + 1) - 18 sin (3 cos (t) + 1) sin (t) - 9 sin (3 cos (t) + 1)

Schritte zur Lösung

4 (3 cos (t) + 1) - (3 sin (t) + 3)^{2} sin (3 cos (t) + 1)

= 4 (3 cos (t) + 1) - sin (3 cos (t) + 1) (3 sin (t) + 3)^{2}

Schreibe

4 (3 cos (t) + 1)

um:

12 cos (t) + 4

= 12 cos (t) + 4 - sin (3 cos (t) + 1) (3 sin (t) + 3)^{2}

Schreibe

- sin (3 cos (t) + 1) (3 sin (t) + 3)^{2}

um:

- 9 sin^{2} (t) sin (3 cos (t) + 1) - 18 sin (3 cos (t) + 1) sin (t) - 9 sin (3 cos (t) + 1)

= 12 cos (t) + 4 - 9 sin^{2} (t) sin (3 cos (t) + 1) - 18 sin (3 cos (t) + 1) sin (t) - 9 sin (3 cos (t) + 1)
