Thanks for all the lectures MIT.

Great video again. I love how you break down and dissect everything, and you do an amazing job of making it easy to follow. These videos have been extremely helpful.

that was brilliant, thank you MIT

Awesome lecture. I really liked the discussion of the solution.

Huge respect for being 40+ older than anyone else teaching math on YouTube. He's pwning newbs on a website he ain't even know how to use.

Where did you get that burgundy sweater. Must know.

This was really good! Thanks sir.

China and Japan are now growing in Death rate greater than Birth rate.

We did a video (featuring the logistic equation) about where equations come from in social science: https://youtu.be/zXY6LEwHgaI

where does that b comes from in the equation?

Very nice! Thanks for the lecture…

What are the steps to the solution at 4.30 ?

Gilbert Strang , The friendly professor!

Thank you sir for this lecture

Excelente clase. ¡Gracias!

Anyone considered the case that the population is 1, not 0 neither a/b? But one person cannot give birth to babies…

In which textbooks would I find these topics? I went through my Calculus textbook – Thomas' Calculus, it didn't cover such problems.

I would thank you professor Gilbert for you wonderful class, otherwise i still don't understand where the "a" in the numerator of the solution y(t) come from ? Thank you in advance for your clarfication

Thank you so much, it is great and really helpful <3
