$1)y= x^{3} -2 x^{2} +x+2 y=3 x^{2} -4x+1$
$2)y=x*(sinx+1) y=1*(sinx+1)+x*cosx$
$3)y= frac{sinx}{ x^{2} +3} y= frac{cosx*( x^{2} +3)-sinx*2x}{ (x2+3)^{2} }$
$4)y=(8x-15)^{5} y=5(8x-15)^{4} *8=40(8x-15)^{4}$
$5)y=sin(4x+ frac{ pi }{6} ) y=cos(4x+ frac{ pi }{6})*4$
$6)y= x^{3} +2x y=3 x^{2} +2$
$7)y=(( sqrt{x} +1)*sqrt{x} ) y= frac{1}{2} x^{- frac{1}{2} } * sqrt{x} +( sqrt{x} +1)* frac{1}{2} x^{- frac{1}{2} }$
$8)y=( frac{6}{x}-2x ) y=-6x^{-2} -2$
$9)y=(2sinx-13) y=2cosx$
$10)y=(3-x)^{5} y=5(3-x)^{4} *(-1)=-5(3-x)^{4}$
$11)y=sin(3x-9) y=cos(3x-9)*3=3cos(3x-9)$
$12)y=cos(5x+7) y=-5sin(5x+7)$
