Q. If −5x3−xy+3−2y=0 then find dxdy in terms of x and y.Answer: dxdy=
Implicit Differentiation: To find the derivative dxdy, we need to differentiate the given equation implicitly with respect to x. Differentiate each term of the equation −5x3−xy+3−2y=0 with respect to x. For −5x3, the derivative is −15x2. For −xy, we apply the product rule: the derivative is −y−xdxdy. For the constant 3, the derivative is 0. For x0, the derivative is x1 because x2 is a function of x.
Derivative Calculation: Combine the derivatives to form the differentiated equation.−15x2−y−xdxdy−2dxdy=0Group the terms with dxdy on one side and the rest on the other side.−xdxdy−2dxdy=15x2+yFactor out dxdy from the left side.dxdy(−x−2)=15x2+y
Combining Derivatives: Solve for (dxdy) by dividing both sides by (−x−2).(dxdy)=−x−215x2+yThis gives us the derivative of y with respect to x in terms of x and y.
