Limit Examples w/ brain malfunction on first prob (part 4)
Sal explores more complex limit problems including showing how to take the limit of an expression with a square root by using the conjugate and how to simplify trigonometric functions that are part of limit problems. Note: A mistake is made on the last step of first problem where multiplication should have been used instead of addition, resulting in the correct answer of 3/16.

Basic Theorems and Proofs
In this pre-calculus worksheet, 11th graders recall the three forms of the law of cosines and used it to solve problems involving triangles. They also write out the laws of sines and use those to solve problems with angles. There are 15 questions.

Supply and Demand
Happy Meals® may have been popular because of the coveted prize that came with the fries. Mathematicians analyze a fictitious BurgerRama campaigning to sell cartoon-character dolls. They graph sales on a chart. In doing so, they examine linear equations for supply and demand.

Home Runs, Statistics, and Probability
Baseball and statistics go hand-in-hand and knowing how to interpret, compare, and display this information is a key skill for any middle schooler. Using two sets of data, have young statisticians answer questions by constructing and comparing different representations of the data especially lineplots (dotplots), stemplots (including back-to-back stemplots) five number summaries, and boxplots.

Introduction to Limits (HD)
Sal begins his explanation of limits with a few basic examples and takes a more intuitive point of view before looking at a formal mathematical definition in later videos. He starts by introducing the notation for limits and describes some of the reasoning that goes into the understanding of limits.

Limit Examples (part 1)
One example, find the limit as x approaches -1 of (2x+2)/(x+1), is solved by simplifying the expression and then is explored intuitively by looking at the left and right-hand limit. The second example of finding the limit as x approaches 0 of 1/x is started here and continued on the part two.

Limit Examples (part 2)
The example of finding the limit as x approaches 0 of 1/x from the first video is completed. Sal continues his explanation of limits by looking at the example of finding the limit as x approaches 0 of 1/x2 to highlight how these two problems yield different solutions.
