“a voice of one calling in the wilderness, ‘Prepare the way for the Lord, make straight paths for him.’”
Mark 1:3 NIV
- Derivative (Wikipedia)
In mathematics, the derivative shows the sensitivity of change of a function’s output with respect to the input. Derivatives are a fundamental tool of calculus. For example, the derivative of the position of a moving object with respect to time is the object’s velocity: this measures how quickly the position of the object changes when time advances.
