12 - What is Exponential Growth & Decay? (Half Life & Doubling Time) - Part 1

In this lesson, you will learn about the exponential function and how exponential growth is mathematically calculated. In addition, we will learn that exponential decay uses a very similar formula, so that once you understand how exponential growth works, you also understand how exponential decay works. For the exponential growth, we will discuss the doubling time, which is the amount of time it takes for the population to double. Similarly, for exponential decay we will consider the half life, which is the amount of time it takes for the population or sample to decay to half of its initial value. These equations come directly from the compound interest formula, which is also an exponential growth formula.

These are all great. I recently bought the streaming membership after watching a few of these. You're one of the best math resources on the web!

Thank you! I might actually pass my inline calc course now! There isn't a professor so I am supposed to learn on my own which is extremely difficult. I am so happy i found these videos and they are truly perfect considering the way learning has moved virtual

This video was so helpful. I actually understand how to do these problems~

[tresajessygeorge]

THANK YOU... SIR...!!!
It is easy... Just have to remember the formula.

Great lectures. Can you do more College Algebra and upload it to the app. Thank you sir.

[EngRiadAlmadani]

Good job can you explain linear algebra with machine learning

Hi Jason! Thanks again for a brilliant teaching lesson. Just a question on a other topic. In winter, why is it that daybreak is colder than the night or day? . I guess it's got to do with thermal energy, please advice? Thanks

A truth is hard to realize and even believe it. Scientific methods relies on experimentation whereas phylosophy depends on the experience to arrive at truth. Anyway they assist one another.

This video could have been more timely. I need to get a better understanding of this topic for my final.
