I caught up with Youthful Savings last week and wrote a short article about Engineer4Free for their blog. They are an awesome NYC startup focused on empowering youth with financial education and entrepreneurship training. Did you know that they give 10% of their earnings back to the community through youth college scholarships? That's pretty amazing, we need more companies like them!
If you'd like to get to know the story behind Engineer4Free or want to check out the Youthful Savings blog, you can read the article here.
The derivative section of calculus is finally complete! (for now). Send requests here if you want a longer explanation or more examples of anything! I might make some videos proving all of the derivative rules later, you would probably never have to prove any of them on a Calculus I exam but sometimes it's nice to know how/why these things work.
