Linear versus Exponential Growth and Decay
Calculus 1, Lectures 3A and 3B
Linear functions are constructed from the arithmetic building blocks of repeated addition and subtraction. In a similar manner, exponential functions are constructed from repeated multiplication and division.
These sentences describe both the most basic similarity … Read the rest
Proportionality and Linear Functions
Calculus 1, Lectures 2A and 2B
Quantities that are directly proportional to each other arise everywhere in science. Examples include distance traveled with speed, volume with temperature for an ideal gas, and force with acceleration.
If the two quantities are thought of as variables, then the direct proportionality between them leads to an equation … Read the rest
The Big Ideas of Calculus
Calculus 1, Lecture 1
Calculus is often described as the mathematics of change. In terms of a short description, this is apt.
You might even say this description gives us a view of the big … Read the rest
