erweitern sec^2(x)(1+cos(x))

Lösung

erweitern

sec^{2} (x) (1 + cos (x))

sec^{2} (x) + sec^{2} (x) cos (x)

Schritte zur Lösung

sec^{2} (x) (1 + cos (x))

Wende das Distributivgesetz an:

a (b + c) = ab + a c

sec^{2} (x) (1 + cos (x)) = sec^{2} (x) \cdot 1 + sec^{2} (x) cos (x)

= sec^{2} (x) \cdot 1 + sec^{2} (x) cos (x)

Apply rule:

a \cdot 1 = a

sec^{2} (x) \cdot 1 = sec^{2} (x)

= sec^{2} (x) + sec^{2} (x) cos (x)

e x p an d \frac{a \cdot s + ( 0.1 \cdot a + 2 \cdot b )}{( s + 0.1 ) ^{3}}

e x p an d (5 x + 4 y) d x

e x p an d x^{2} (x x - 2) + π

e x p an d (4 x - 1) (x^{\frac{1}{3}} + 5 x + 2)

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