if:
2x3+8lny+x3ey-16-8e=0
what i did was
dy/dx=[tex]\dot{y}[/tex]
6x2+8(1/y)[tex]\dot{y}[/tex]+3x2ey+x3ey[tex]\dot{y}[/tex]=0
[tex]\dot{y}[/tex]=-(x2(6+3ey)/(8/y+x3ey)
then to find the incline of the normal, m=-1/[tex]\dot{y}[/tex]
so at(2,1)
[tex]\dot{y}[/tex]=-3(2+e)/2(1+e)
m(N)=2(1+e)/3(2+e)
does this seem right??
Y-1=[2(1+e)/3(2+e)]{x-2}
