erweitern z((cos(t))^2+(sin(t))^2+4z^2=4)

Lösung

erweitern

z ((cos (t))^{2} + (sin (t))^{2} + 4 z^{2} = 4)

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

Schritte zur Lösung

z ((cos (t))^{2} + (sin (t))^{2} + 4 z^{2} = 4)

= z ((cos (t))^{2} + (sin (t))^{2} + 4 \cdot 4 = z^{2})

Setze Klammern

z (cos (t))^{2} + z (sin (t))^{2} + z \cdot 4 z^{2} = 4

z (cos (t))^{2} + z (sin (t))^{2} + 4 z^{2} z = 4
