erweitern cos(x)(sec(x)+3,x)

Lösung

erweitern

cos (x) (sec (x) + 3, x)

cos (x) sec (x) + 3 cos (x), x

Schritte zur Lösung

cos (x) (sec (x) + 3, x)

Wende das Distributivgesetz an:

a (b + c) = ab + a c

a = cos (x), b = sec (x), c = 3, x

= cos (x) sec (x) + cos (x) \cdot 3, x

= cos (x) sec (x) + 3 cos (x), x

s im pl i f y (a + 5) (a - 5)

e x p an d - 4 (x + 2) (- \frac{1}{4} = \frac{x}{- 4 ( x + 2 )})

e x p an d \frac{x ( x + 3 )}{x ^{2} + x - 12}

s im pl i f y (\frac{2}{x + 2} + x) \cdot x

e x p an d y \cdot lo g_{10} (x) + (1 - y) \cdot lo g_{10} (1 - x + z)
