A-level曲线的切线数学题
The curve C has equation y=x2(x-6)+4/x p(1,-1) Q(2,-14)
Show that the tangents to C at p and Q are parallel
A-level曲线的切线数学题The curve C has equation y=x2(x-6)+4/x p(1,-1) Q(2,-14)Show that the tangents to C at p and Q are parallel
曲线C的导数y'=3x^2-12x-4/x^2
x=1时,y'=-13
x=2时,y'=-13
所以过P和Q的切线是平行的.
