Q. If y3+5y−x2+1=0 then find dxdy in terms of x and y.Answer: dxdy=
Implicit Differentiation: Differentiate both sides of the equation with respect to x. We will use implicit differentiation because y is a function of x. Differentiate y3 with respect to x: 3y2(dxdy) Differentiate 5y with respect to x: 5(dxdy) Differentiate −x2 with respect to x: y1 Differentiate y2 with respect to x: y4
Write Differentiated Equation: Write down the differentiated equation.3y2dxdy+5dxdy−2x=0
Solve for (\frac{dy}{dx}): Solve for \((\frac{dy}{dx}).\(\newlineFactor out (\frac{dy}{dx}) from the terms that contain it:\(\newline(\frac{dy}{dx})(\(3y^2 + 5) = 2xNow, divide both sides by (\(3y^2 + 5) to isolate (\frac{dy}{dx}):\(\newline\((\frac{dy}{dx}) = \frac{\(2\)x}{\(3\)y^\(2\) + \(5\)}
