Hello all,
I am having trouble with the following:
Given the plane curve:
y^4 + 2x^2 - 2y^2 = 0
Find the equation for the slope of the tangent line to the curve.
I think you use implicit differentiation, but it is not covered very well in my textbook, and am going mental trying to figure this out!
Any help is much appreciated,
Dranalion.
Mr fantastic's point is: Don't use "x" as a variable and to represent multiplication in the same equation. In fact, even if there doesn't happen to be an "x" in the equation it is very confusing to use "x" to represent multiplication. Use standard algebra notation instead.
