Q. If −5y3−xy−x=−2 then find dxdy in terms of x and y.Answer: dxdy=
Differentiate Equation: Differentiate both sides of the equation with respect to x. We will use the power rule for differentiating y3, the product rule for differentiating xy, and the constant rule for differentiating constants. dxd(−5y3−xy−x)=dxd(−2)
Apply Differentiation Rules: Apply the differentiation rules to each term.For −5y3, since y is a function of x, we use the chain rule and get −15y2dxdy.For −xy, we apply the product rule and get −y−xdxdy.For −x, the derivative is −1.For −2, the derivative is 0.So, y0
Rearrange to Solve: Rearrange the terms to solve for dxdy. Combine like terms and factor out dxdy. dxdy(−15y2−x)=y+1
Isolate dxdy: Isolate dxdy.Divide both sides by (−15y2−x) to solve for dxdy.dxdy=−15y2−xy+1
