本人将去新加破留学
请教几个问题
(1)The gradient of a curve at any point is given by dy/dx=4/根号下(2x+4) Given also that the curve passes through the points (6,8)and(16,K),find the value of k.
(2)The equation of the normal to the curve y={ax2(2是x的平方)+b}/x
at the point P(1,-6) is x+10y+59=0
find the value of a and b.
请讲的细一点,如果有新加坡中学数学资料的网站请给几个.
谢谢
请给出解题答案

曲线的梯度在任一点由dy/dx=4/ 给根号下(2x+4) 并且给, 曲线通过点(6,8)and(16,K),find k 的价值。
(2)The equation of the normal to the curve y={ax2(2是x的平方)+b}/x
at the point P(1,-6) is x+10y+59=0
find the value of a and b.
法线的等式对曲线y={ax2(2是x的平方)+b}/x
在点P(1, -6) 是x+10y+59=0
发现a 和b 的价值。
