Пошаговое объяснение:
1) y = 12x+√x ; y' = ( 12x+√x )' = ( 12x )' + ( √x )' = 12 + 1/(2√x ) ;
2) y = 1/x + 4x ; y' = ( 1/x + 4x )' = ( 1/x )' + ( 4x )' = - 1/x² + 4 ;
3) y = 6√x+3x ; y' = ( 6√x+3x )' = ( 6√x )' + ( 3x )' = 6/2√x+3 = 3/√x+3 ;
4) y = sin x + 3 ; y'= ( sin x + 3 )' = ( sin x )' + 3 ' = cosx + 0 = cosx ;
5) y = cos x + 2x ; y' = ( cos x + 2x )' = ( cos x )' + ( 2x )' = - sin x + 2 .
