Find , when:
xy² — x²y — 5 = 0

Let us differentiate the whole equation w.r.t x

Formula :

According to chain rule of differentiation

According to product rule of differentiation

Therefore ,

Find , when:

xy = c²

Find , when:

x² + y² — 3xy = 1

Find , when:

(x² + y²)² = xy

Find , when:

x² + y² = log (xy)
