If anyone could check this answer for me, it would be greatly appreciated.
Find the equations relating the differentials on the curve [tex] 9y^2= x^3 +3x^2 [/tex] at the points [tex] (1,\frac{2}{3}), (-2,\frac{2}{3}), (-3,0) [/tex]
Here's what I got:
[tex] y'= \frac {x^2+2x}{6y} [/tex]
[tex] m @ (1,\frac{2}{3})= \frac {3}{4} [/tex]
equation: 9x-12y-1=0
[tex] m @ (-2,\frac{2}{3})=0 [/tex]
equation: y= 2/3
[tex] m @ (-3,0) [/tex]
does not exist
Thanks in advance.
