Final answer:
To find y" by implicit differentiation for the equation x² - 7y² = 7, differentiate both sides of the equation with respect to x using the chain rule and solve for y".
Step-by-step explanation:
To find y" by implicit differentiation for the equation x² - 7y² = 7, we need to differentiate both sides of the equation with respect to x using the chain rule. Let's go step by step:
- Differentiate x² with respect to x to get 2x.
- Differentiate -7y² with respect to x using the chain rule. The derivative of -7y² with respect to y is -14y. Then multiply it by the derivative of y with respect to x, which is y'.
- Set the resulting expression equal to 0 to get the second derivative.
- Solve for y" by isolating the y" term.
After following these steps, you should end up with the expression for y". Remember to simplify as much as possible.
