Lösung

löse nach

t, cot (x) cot^{2} (x) = - 1

Wahr f \overset{u}{¨} r alle t; cot^{3} (x) = - 1

Schritte zur Lösung

cot (x) cot^{2} (x) = - 1

Vereinfache

cot (x) cot^{2} (x) : cot^{3} (x)

cot (x) cot^{2} (x)

Wende Exponentenregel an:

a^{b} \cdot a^{c} = a^{b + c}

cot (x) cot^{2} (x) = cot^{1 + 2} (x)

= cot^{1 + 2} (x)

Addiere die Zahlen:

1 + 2 = 3

= cot^{3} (x)

cot^{3} (x) = - 1

Beide Seiten sind gleich

Wahr f \overset{u}{¨} r alle t; cot^{3} (x) = - 1

so l v e f or i, 1 - 2 sin^{2} (4 5^{\circ} - \frac{a}{2}) = sin (a)

so l v e f or c, sin^{2} (x) + sin (x) - cos (x) + \frac{1}{2} = 0

so l v e f or c, cos^{4} (s) - sin^{4} (x) + 1 + cos (x) = 0

so l v e f or c, cot^{2} (x) = cos (x) + sin (x)

so l v e f or y, y = sin (3 t) u (t) \cdot u (t)
