erweitern sin(x)(sec(x)-sqrt(2))

Lösung

erweitern

sin (x) (sec (x) - 2)

tan (x) - 2 sin (x)

Schritte zur Lösung

sin (x) (sec (x) - 2)

Wende das Distributivgesetz an:

a (b - c) = ab - a c

sin (x) (sec (x) - 2) = sin (x) sec (x) - sin (x) 2

= sin (x) sec (x) - sin (x) 2

Vereinfache

sin (x) sec (x) - sin (x) 2 : tan (x) - 2 sin (x)

= tan (x) - 2 sin (x)

s im pl i f y (3 u - u + 3) (2 u + u + 3)

s im pl i f y (cos (x) + sec (x))^{2} + sin^{2} (x) - tan^{2} (x) + 3

e x p an d (\frac{1}{2} - \frac{3}{2} i)^{16}

e x p an d (x^{\frac{1}{2}} + 2)^{2}

e x p an d \frac{( e ^{2} + 1 ) ( e + 1 ) ( e - 1 )}{2 e ^{2}}
