WebFinding the derivative explicitly is a two-step process: (1) find y in terms of x, and (2) differentiate, which gives us dy/dx in terms of x. Finding the derivative implicitly is also two steps: (1) differentiate, and (2) solve for dy/dx. This method may leave us with dy/dx in terms of both x and y. WebIn implicit differentiation, we differentiate each side of an equation with two variables (usually x x and y y) by treating one of the variables as a function of the other. This calls for using the chain rule. Let's differentiate x^2+y^2=1 x2 +y2 = 1 for example. Here, we …

WebNov 16, 2024 · In this case we call h′(b) h ′ ( b) the partial derivative of f (x,y) f ( x, y) with respect to y y at (a,b) ( a, b) and we denote it as follows, f y(a,b) = 6a2b2 f y ( a, b) = 6 a 2 b 2.
