Finding an equation of best fit in Desmos

Go to Desmos.com and choose Start Graphing. In the upper left, choose Add Item > table. Type your data in the table. Click on the wrench in the upper right to change the graph settings. Modify your x, and y values to reflect your data. Decide what type of equation the data represents. In the example [...]

Functions and their Graphs

Reviewing Parent Functions In Pre-Calculus class we dove right in and reviewed five of our parent functions. Screen shots of Reviewing Parent Functions Geogebra Activity are shown below. I will likely rework it next year to include a slider for a variable "b" that reflects across the y-axis and horizontally stretches/shrinks the graph. I made [...]

Polynomial and Rational Functions

Polynomial Functions Pre-Calculus has a heavy emphasis on learning how to graph various functions. The Polynomial Functions Exploration is one strategy for learning how various functions behave based on the sign of their leading coefficient and the highest power of the polynomial. I find that my students remember functions ending behavior better when they discover [...]

Midpoint

One frustration I encountered last year in my geometry classes involved the Distance and Midpoint formulas. Our text book and I made the assumption that since my students had worked with these formulas, they would remember them and could use them. We encountered problems throughout the book that required the use of both formulas and I [...]

Graphing Polar Equations

We have spent some time learning how to graph circles, limacons, rose curves, and lemniscates on the polar coordinate plane. The material you see below is borrowed heavily from Yosh's Graphing Polar Equations part 1, part 2, and part 3. I have included a link to the Word document instead of a pdf of the [...]

Chords, Secants and Tangents, Oh my!

When starting a new unit on circles, I'm cognizant of how important learning the vocabulary is. Most geometry students are only familiar with the center, radius and diameter of a circle. Following a trigonometry unit, the word tangent takes on  a new meaning. The following notes sheets and study guides should help address this. Lines & Segments that [...]
