erweitern sec(x)(1-cos(x)=sec(x)-1)

Lösung

erweitern

sec (x) (1 - cos (x) = sec (x) - 1)

sec (x) - sec (x) cos (x) = 0

Schritte zur Lösung

sec (x) (1 - cos (x) = sec (x) - 1)

= sec (x) (1 - = cos (x) sec (x) - 1)

Setze Klammern

= sec (x) \cdot 1 + sec (x) (- cos (x) = sec (x)) + sec (x) (- 1)

1 \cdot sec (x) - sec (x) cos (x) = sec (x) - 1 \cdot sec (x)

Vereinfache

1 \cdot sec (x) - sec (x) cos (x) = sec (x) - 1 \cdot sec (x) : sec (x) - sec (x) cos (x) = 0

sec (x) - sec (x) cos (x) = 0
