Introduction to Derivatives
Derivatives are a fundamental concept in calculus and represent the rate of change of a function with respect to a variable. They are used extensively in various fields such as physics, engineering, and economics.
Here is a simple representation of a derivative in graphical form:
Basic Rules of Differentiation
- The Power Rule: d/dx (xn) = nxn-1
- The Constant Rule: d/dx (c) = 0 where c is a constant
- The Sum Rule: d/dx (u + v) = du/dx + dv/dx
Common Applications
Derivatives are often used to find the slope of a curve at a point, calculate motion variables, and optimize situations by finding maximum and minimum values.
