### Q: How can you find the real and imaginary parts of a function using complex numbers?

To find the real and imaginary parts of a function, replace the complex number with its components, where the real part corresponds to the real number, and the imaginary part corresponds to the imaginary part multiplied by the imaginary unit (i).

### Q: What equation needs to be satisfied by the real and imaginary parts?

The equation that needs to be satisfied by the real and imaginary parts states that the sum of the second partial derivatives of the function with respect to x and y is equal to zero.

### Q: How can you verify that the real and imaginary parts satisfy the equation?

To verify that the real and imaginary parts satisfy the equation, calculate the second partial derivatives of each part with respect to x and y, then add them together. If the sum is equal to zero for both parts, the equation is satisfied.

### Q: What is the significance of verifying the real and imaginary parts?

Verifying that the real and imaginary parts satisfy the equation ensures that the function is in compliance with the requirements of the equation and can be used reliably for further analysis.
