#### Course Description

This course is designed to develop basic algebraic skills through a study of fundamental properties of numbers, fundamental operations in arithmetic and algebra, including polynomials and linear equations. It is intended for both first-time students and those wishing to brush up on their algebra skills.

This is one of my favorite courses to teach because this is where your foundation in algebra begins and I'd like to help build or repair your foundation.

This course, taught on campus twice per week for 75 minutes each, was primarily recorded at the Lancaster Campus of Harrisburg Area Community College. The video recordings are predominantly unedited clips from live classes.

The prerequisite for this course is pre-algebra.

This course requires the use of a scientific calculator (graphing calculator not necessary).

After each lesson you will perform a self-assessment to monitor your progress in the course. An estimated time needed to perform each self-assessment is stated in each post. Answer keys for each self-assessment are provided in each post.

**You will NOT get any credit from taking this course in iTunes U though. You need to enroll as a regular or online student to receive credits. Please visit these web sites for more information.**http://www.hacc.edu/

4 | Free Graphing Calculator | *** Now over 4 million downloads. Thanks users!*** A powerful, flexible graphing calculator . . . and it's free! Does far more than most of the paid calculators out there . . . let alone the free ones. Features: 1) Scientific Calculator. Simple to grasp and easy to use, but powerful features are available when you need them. Available functions include the following: • the usual arithmetic functions and exponentiation. • square root, cube root, nth root, natural log, log base 10, log of arbitrary base, absolute value, factorial, permutations (nPr), combinations (nCr), modulus, random integer, bell curve, cumulative normal distribution, decimal to fraction. 2) Graphing. Capabilities: • Graph up to four equations at once. • Graphs are labeled. • You can drag the graph or pinch to zoom in or out. • Calculator can find roots and intersections. • Graph in polar coordinates. • Graph parametric equations • Can graph implicit functions, such as x^2+y^2-4=0. Most calculator apps can't do this! 3) A unit converter. With a tap, you can enter the result of your conversion into the calculator. Currently converts different units of the following: acceleration, angle, area, density, distance, energy, force, mass, power, pressure, speed, temperature, time, and volume. Great for doing physics homework! 4) Constants for scientific calculations -- speed of light, strength of gravity at Earth's surface, etc. etc. etc. Tapping on a constant will insert it into your calculation -- i.e, you don't have to key in the value. Again, great for doing physics homework! 5) It can make a table of the values of any function you care to enter. You can choose the starting x value of the table, as well as how much x increases for each successive row. 6) Help screens linked directly to many of the available functions and constants. Tap the disclosure arrow to see the definition. 7) Forgot the quadratic formula? Or the double-angle formulas for sine and cosine? The math/science reference hits the high points of various subjects. Currently includes algebra, differential and integral calculus, geometry, trigonometry, vectors, vector calculus, and classical mechanics. 8) Keep track of significant figures [AKA sig figs] 9) Statistics -- enter data and make a histogram, box and whisker plot, or scatter plot with optional regression line. If you are viewing this in iTunes, you will see five iPhone screenshots and five iPad screenshots. But even ten shots don't come close to showing everything this calculator can do. I'd love to hear your comments or suggestions. You can write me at mathscixyzgraphcalc@gmail.com -- but without the xyz. Thanks! | -- | Free | View In iTunes |
