Civil Engineering QUESTION #6564
Question 1
Mathematically, a differential is best described as:
  • A technique used for mathematical modeling
  • A method that directly relates how changes in an independent variable affect changes in a dependent variable
  • A method that directly relates how changes in a dependent variable affect changes in an independent variable✔️
  • None of the above
Correct Answer Explanation
A differential expresses the relationship: \(dy = f'(x)\,dx\), showing how a small change in the independent variable \(x\) produces a change in the dependent variable \(y\).
