Q. If −5x−3xy+y2=0 then find dxdy in terms of x and y.Answer: dxdy=
Identify Equation: Identify the equation that needs to be differentiated with respect to x.−5x−3xy+y2=0We will use implicit differentiation to find dxdy.
Differentiate with Respect: Differentiate both sides of the equation with respect to x. The derivative of −5x with respect to x is −5. The derivative of −3xy with respect to x is −3y−3xdxdy because it is a product of two functions (use the product rule). The derivative of y2 with respect to x is 2ydxdy because it is a function of −5x0 (use the chain rule). The derivative of −5x1 with respect to x is −5x1. So, we have −5x4.
Combine and Solve: Combine like terms and solve for dxdy.−5−3y=3xdxdy−2ydxdy Group the terms with dxdy on one side of the equation.(3x−2y)dxdy=5+3y
