Where is Plan B when you need it? ^^^^ at home i guess three question marks

meh

$$e_{123}$$

Beispiel
a) Vektorraum aller über $$[a,b]$$ definierten reellwertigen Funktionen

$$f(x),g(x) \in\mathbb R$$

$$( f(x),g(x) ) = \int_a^b f(x)g(x)dx$$

Nur Nichtnegativität:

$$( f(x),g(x) ) = \int_a^b f(x)g(x)^2dx$$ !!!EIN BILD DAZU

b) Vektorraum $$\mathbb R$$: n-Tupel aus reellen Zahlen

$$x, y \in\mathbb R^n$$

$$(x,y)=\sum_{i=1}^{n} x_i y_i$$ ; andere Schreibweise : $$(x,y)=x^T*y$$

Eigenschaften zur Folie 47

$$(x,y)=0 \and (x,z)=0 \to (x, \lambda y + \mu z)=0$$

mit $$(x,y)=\sum_{i=1}^{n} x_i y_i$$ folgt
