Homework Statement
Back for more questions. This section has been pretty tricky.
The graph of a folium with equation ##2x^3+2y^3-9xy=0## is given.
Find the equation for the tangent line at the pont ##(2,1)##
Find the equation of the normal line to the tangent line in the last question at the point (2,1).
Homework Equations
The Attempt at a Solution
From part a, the tangent line at the point ##(2,1)## is ##y=\frac{5}{4}x-\frac{3}{2}##
Now by "normal" line, I assume that the question is talking about the folium itself.
But since we're talking about the line at that point, wouldn't the equation for the normal line at that exact point just be the tangent line? Otherwise, how could we determine how far out to choose our x values?
