Implementation of a function in GNU R We define the function $f_{a}:\mathbb {R} ^{3}\to \mathbb {R}$ with an example evaluation $f_{a}(4,2,1)=15$ .

   f_a <- function (px) {
    ## px : Vektor - unabhängige Variable
    a <- c(1,3,5)
    return <-  sum(a * px)
    ## Rückgabewert: return Berechneter y-Wert für Parameter px 
    return
  }
  
  ## Aufruf der Funktion für den Vektor x
  x <- c(4,2,1)
  f_a(x) ## Ergebnis 15

Inline Math Expression in Slides

The condition that U be simply connected means that U has no "holes" or, in homotopy terms, that the fundamental group of U is trivial; for instance, every open disk $U=\{z:|z-z_{0}|<r\}$ qualifies. The condition is crucial; consider
