# Implicit derivative at a particular point

For the function f(x,y) = x^3 + y^3 - 6*x*y, what will be input command in sage math for calculation of dy/dx at (1,2).

Sample question: How do I compute symbolic integrals like $\int{sin(x) tan(x)} dx$

How do I understand the result of symbolic integrals

why is symbolic comparison so slow?

We can find implicit derivative as follows x = var('x') y = var('y')

f(x,y) = x^3 + y^3 - 6

xyy=function('y')(x) temp=diff(f(x,y)) solve(temp,diff(y))

But my question is how we can find the value of implicit derivative at point (1,2)
