erweitern (a^2-b^2-c^2)tan(a)+(a^2-b^2+c^2)tan(b)

Lösung

erweitern

(a^{2} - b^{2} - c^{2}) tan (a) + (a^{2} - b^{2} + c^{2}) tan (b)

a^{2} tan (a) - b^{2} tan (a) - c^{2} tan (a) + a^{2} tan (b) - b^{2} tan (b) + c^{2} tan (b)

Schritte zur Lösung

(a^{2} - b^{2} - c^{2}) tan (a) + (a^{2} - b^{2} + c^{2}) tan (b)

= tan (a) (a^{2} - b^{2} - c^{2}) + tan (b) (a^{2} - b^{2} + c^{2})

Schreibe

tan (a) (a^{2} - b^{2} - c^{2})

um:

a^{2} tan (a) - b^{2} tan (a) - c^{2} tan (a)

= a^{2} tan (a) - b^{2} tan (a) - c^{2} tan (a) + tan (b) (a^{2} - b^{2} + c^{2})

Schreibe

tan (b) (a^{2} - b^{2} + c^{2})

um:

a^{2} tan (b) - b^{2} tan (b) + c^{2} tan (b)

= a^{2} tan (a) - b^{2} tan (a) - c^{2} tan (a) + a^{2} tan (b) - b^{2} tan (b) + c^{2} tan (b)
