erweitern (sec(x)+,-1)(sec(x)-,+1)

Lösung

erweitern

(sec (x) +, - 1) (sec (x) -, + 1)

sec (x) sec (x) - sec (x), 1 \cdot sec (x), sec (x),, +, 1 - 1 \cdot sec (x) + 1, - 1 \cdot 1

Schritte zur Lösung

(sec (x) +, - 1) (sec (x) -, + 1)

Setze Klammern

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

Wende Minus-Plus Regeln an

+ (- a) = - a, (- a) (- b) = ab

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

e x p an d \frac{x ^{4} ( 16 x ^{2} y ^{6} + 3 ) ^{2}}{16}
