((- cos (x)) + cos (x)) in t er v a l [- \frac{π}{4}, π]

e [- π \frac{π}{4},] l in t r v a (- cos (x)) + e [- π \frac{π}{4},] l in t r v a cos (x)

Schritte zur Lösung

((- cos (x)) + cos (x)) in t er v a l [- \frac{π}{4}, π]

= e [- π \frac{π}{4},] l in t r v a ((- cos (x)) + cos (x))

Wende das Distributivgesetz an:

a (b + c) = ab + a c

a = in t er v a l [- \frac{π}{4}, π], b = (- cos (x)), c = cos (x)

= in t er v a l [- \frac{π}{4}, π] (- cos (x)) + in t er v a l [- \frac{π}{4}, π] cos (x)

= e [- π \frac{π}{4},] l in t r v a (- cos (x)) + e [- π \frac{π}{4},] l in t r v a cos (x)

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

e x p an d (x + e^{x}) (y)

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

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

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