Question

Calculate the derivative of xy + sin(x) = e^y with respect to x

Answer

Let’s break down how to find the derivative of with respect to .
1. Implicit Differentiation
Since we have mixed in with terms, we’ll use implicit differentiation. This means we’ll differentiate both sides of the equation with respect to , treating as a function of .
2. Applying the Derivative Rules
  • Product Rule: For the term , we’ll use the product rule:
    d(uv)/dx = u(dv/dx) + v(du/dx)
  • Chain Rule: Since is a function of , we’ll use the chain rule when differentiating terms involving . For example, the derivative of with respect to is .
Step-by-Step Solution
  1. Differentiate both sides:
  2. Apply the product rule to xy:
  3. Isolate dy/dx terms:
  4. Factor out dy/dx:
  5. Solve for dy/dx:
Therefore, the derivative of xy + sin(x) = e^y with respect to x is:
