| Implicit differentiation 1 |   |
| If an equation in x and y is given, where neither x nor y are the subject of the equation, then the equation is known as an implicit equation. Some examples: | |
| x²+y² = 4, 4x + 6xy + 5y² = 0, sin x - 3cos y = 0.3 | |
| Such equations can be differentiated using adaptations of the chain rule and product rule. | |
