Allgemein zu 1. und 2.
[ x^{term} ] = term * x (term-1)
1) [ f ( x ) ]´ = [ x2k+1 ]´ = ( 2k + 1 ) * x^{2k+1-1} = ( 2k + 1 ) * x^{2k
3} f(x) = 3√ x schreiben wir
f ( x ) = x^{1/3}
[ f ( x ) ] ´ = 1/3 * x^{1/3-1} = 1 / 3 * x^{-2/3}
1 / 3 * 1 / x^{2/3}
1 ( ( 3 * 3√x^2 )
4) f(x) = 3√x - 2x2
f ´( x ) = 3 / ( 2 * √x ) - 4 * x
