Q. If 3y2−4x3=3x2 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: 3y2−4x3=3x2. We will use implicit differentiation because y is a function of x.
Differentiate with Respect: Differentiate both sides of the equation with respect to x. The left side of the equation, 3y2, becomes 6ydxdy because of the chain rule. The term −4x3 becomes −12x2. The right side of the equation, 3x2, becomes 6x.
Write Differentiated Equation: Write down the differentiated equation.6ydxdy−12x2=6x
Isolate Term with dxdy: Isolate the term with dxdy on one side of the equation.6ydxdy=12x2+6x
Divide and Solve for dxdy: Divide both sides of the equation by 6y to solve for dxdy.dxdy=6y12x2+6x
Simplify Right Side: Simplify the right side of the equation. (dxdy)=y2x2+x
