sorry this is so late.... two weeks ago in class we learned about probability. We learned about sample spaces and focused on probability using dice and cards.

We started class today by watching a Formula 1 Racing video, which was really cool but which also led to one of the topics we covered in class- velocity. We realized that it at one point in time, an object is not moving (think of a snapshot: in a picture, an object is stationary). The solution to that problem was the term instantaneous velocity.
In addition to this, we learned about finding the slope of the line tangent to a given graph at a certain point, also called the derivative, and finding the formula for the slope of a line tangent to a given graph at any point on the graph.

Limits with piecewise functions, One-sided limits, and More Algebra with Limits


We started class today by going over the homework from the night before (4/30). We then started talking about the limits of piecewise functions and one-sided limits, which is when you determine the limit of something by looking at it from either the positive or negative direction. This is indicated by having a + or - superscript. We then had more examples of algebra with limits.
