设曲线[img=114x26]1803d354f531134.png[/img]在点M处的切线与直线4y + x + 1 =0垂直,则该曲线在点M处的切线方程是( )
A: 16x - 4y - 17 = 0
B: 16x + 4y - 31 = 0
C: 2x - 8y + 11 = 0
D: 2x + 8y - 17 = 0
A: 16x - 4y - 17 = 0
B: 16x + 4y - 31 = 0
C: 2x - 8y + 11 = 0
D: 2x + 8y - 17 = 0
举一反三
- 双曲线x^2/16-y^2/9=1的渐近线方程为() A: y=±16x/9 B: y=±9x/16 C: x/3±y/4=0 D: x/4±y/3=0
- 直线 y = 0 是曲线 y = | x | 在点(0 , 0)处的切线.
- 曲面[img=109x23]1803d350bf21608.png[/img]在点(2,1,0)处的切平面为( ) A: x + 2y - 1 = 0 B: x + y - 4 = 0 C: 2x + y - 4 = 0 D: x + 2y - 4 = 0
- 过曲线[img=134x23]1803d342e04c06f.png[/img]上的点(0,1)处的法线方程为 ( ) A: 2x - y + 1 = 0 B: x - 2y + 2 = 0 C: 2x - y - 1 = 0 D: x + 2y - 2 = 0
- 由方程[img=132x22]17e0b6947592de6.jpg[/img]确定的曲线在点(0,0)处的切线方程是. A: x=0 B: y=0 C: y=x D: y=-x
