How to Make a Demand Equation

Today I was doing a calculus problem where I had to make a demand equation and it really gave me a hard time.

I finally found a really great video that explains it. Here is the link

A Math Joke in the Simpsons by PatrickJMT

Looking for help with math?

PatrickJMT is one of my go to sources for math help. His youtube tutorials are easy to understand and just great.

Here is a fun video he made about  a joke in a Simpsons episode with some fun math in it.


So You Want to Study Geometry

I am in my 60's and I am studying calculus and kinematics. I need them for some advanced work I am doing. You have my permission to study both basic and advanced at the same time.   One moment I'm looking at the Introduction to Electromagnetism by Griffiths or The Evolution of Physics by Albert Einstein, and the next moment it's The Isaac Newton School of Driving or Barrons's AP Physics. Remember "learning is s'posed to be fun."

You know what--I really have benefited from Youtube videos. For calculus, PatrickJMT, Dereck Owens, That Tutor Guy, and Dr. Schuster have been very helpful. For kinematics, Mrs. Twu and Bozeman Science.

I watch a video or two, and then go to that section in my book. Then back to the videos again. And so on.  

But how about geometry? Geometry is somewhat overlooked. But luckily, there is Khan Academy to the rescue.

For trig Patrickjmt again  and also ProfRobBob for trig identities

Interactive Teaching, Whiteboarding, and Some Great Content for Teachers

What are Whiteboards?
  • 32" x 24" pieces of white tile board
  • written on with dry erase markers, cleaned with paper napkins
Now they have whteboards everywhere. Shopko, Walmart, Office Depot and so on.

In fact I found a nice little whiteboard at the DollarTree for only one dollar each. I got two of them and I use them all the time.

But here are a couple of internet places just in case you are needing something online.

small boards

Small boards personal sine are great, but I guess the idea is to find 24X36 without frames so they are easy for 2 students to work on collaboratively.
