Q. If y2x23=0 y^{2}-x^{2}-3=0 then find dydx \frac{d y}{d x} in terms of x x and y y .\newlineAnswer: dydx= \frac{d y}{d x}=
  1. Given Equation: We are given the equation y2x23=0y^{2} - x^{2} - 3 = 0 and we need to find the derivative of yy with respect to xx, denoted as dydx\frac{dy}{dx}. To do this, we will use implicit differentiation, which involves taking the derivative of both sides of the equation with respect to xx.
  2. Differentiate y2y^2: First, we differentiate y2y^{2} with respect to xx. Since yy is a function of xx, we use the chain rule and get 2ydydx2y \cdot \frac{dy}{dx}.
  3. Differentiate x2-x^2: Next, we differentiate x2-x^{2} with respect to xx, which is straightforward and equals 2x-2x.
  4. Differentiate constant: The derivative of the constant 3-3 with respect to xx is 00, since the derivative of any constant is 00.
  5. Combine and set equal: Now we combine the derivatives from the previous steps and set the derivative of the entire left side of the equation equal to the derivative of the right side, which is 00. This gives us the equation 2ydydx2x=02y \cdot \frac{dy}{dx} - 2x = 0.
  6. Isolate (dy)/(dx)(dy)/(dx): We solve for (dy)/(dx)(dy)/(dx) by isolating it on one side of the equation. To do this, we add 2x2x to both sides to get 2y(dy)/(dx)=2x2y \cdot (dy)/(dx) = 2x.
  7. Divide by 2y2y: Finally, we divide both sides of the equation by 2y2y to solve for dydx\frac{dy}{dx}. This gives us dydx=2x2y\frac{dy}{dx} = \frac{2x}{2y}.
  8. Simplify expression: We can simplify the expression 2x2y\frac{2x}{2y} by canceling out the 22s, which leaves us with dydx=xy\frac{dy}{dx} = \frac{x}{y}.
