Q. If −2y3=1+x3 then find dxdy in terms of x and y.Answer: dxdy=
Write Equation: Write down the given equation.The given equation is −2y3=1+x3.
Differentiate with Respect: Differentiate both sides of the equation with respect to x. To find dxdy, we need to differentiate both sides of the equation with respect to x. Remember that y is a function of x, so when differentiating terms with y, we use the chain rule. dxd(−2y3)=dxd(1+x3)
Apply Chain and Power Rule: Apply the chain rule to the left side and the power rule to the right side.Using the chain rule on the left side, we get −6y2⋅dxdy. On the right side, the derivative of 1 is 0, and the derivative of x3 is 3x2.−6y2⋅dxdy=0+3x2
Solve for (dxdy): Solve for (dxdy). To solve for (dxdy), we divide both sides of the equation by −6y2. (dxdy)=−6y23x2
Simplify Expression: Simplify the expression for (dxdy). We can simplify the fraction by dividing the numerator and the denominator by 3. (dxdy)=−2y2x2
