Schnittpunkt f(x) = g(x)
(x + 3) * e-0,5x = e-0,5x
x + 3 = 1
x = -2
g(-2) = e^{-0.5*-2} = e^1 = e
Schnittpunkt S(-2 | e)
Schnittwinkel
f '(x) = e^{- 0.5·x}·(-0.5x - 0.5)
g '(x) = - 0.5·e^{- 0.5·x}
arctan(f '(-2)) = arctan(e/2) = 53.66°
arctan(g '(-2)) = arctan(-e/2) = -53.66°
53.66° - (-53.66°) = 107.3°
