Tips on how to get the most usage out of your calculator. No previous knowledge assumed.

This video is to help students in math and science classes learn the Greek alphabet. The pronunciation is the English way of saying the letters in an American accent. It is NOT meant for those actually   more...trying to learn Greek as a foreign language.  less

[NOTE: This video is only the first 11 minutes of the full lesson, please visit my web site to purchase complete version] This lesson consists of providing you with a Self-Tutorial on what is algebra,   more...what are variables, constants, coefficients, terms, and expressions. I explain the use of proper notation, how to combine like terms, find the negation of an algebraic expression, how to evaluate an expression (by hand and by using your calculator), and finally, there is a VERY detailed section on how to translate English phrases into algebraic expressions.  less

Graph plotter program plots 2D graphs from complex equations. The application comprises algebraic, trigonometric, hyperbolic and transcendental functions. EqPlot can be used to verify the results of nonlinear   more...regression analysis program.
Equation graph plotter gives engineers and researchers the power to graphically review equations, by putting a large number of equations at their fingertips. The program is also indispensable for students and teachers.
A flexible work area lets you type in your equations directly. It is as simple as a regular text editor. Annotate, edit and repeat your graphings in the work area. You can also paste your equations into the editor panel.
Example of mathematical expression:
5.22 - (2 * x) + square(x) + power(x;3) + power(2.55;4) - logbaseN(4;6.25)
Save your work for later use into a text or graphic file. Comprehensive online help is easily accessed within the program.
Features:
--------
*Scientific graphings
*Unlimited expression length
*Parenthesis compatible
*Scientific notation
*More than 35 functions
*More than 40 constants
*User-friendly error messages
*Simple mode (medium size on desktop)
*Paste expressions into EqPlot
*Online documentation
*All the benefits that Windows bestows, such as multi-tasking and print formatting are available  less

DataFitting program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions. The regression analysis determines   more...the values of the parameters that cause the function to best fit the observed data that you provide. This process is also called curve fitting.
DataFitting gives engineers and researchers the power to find the ideal model for even the most complex data, by putting a large number of equations at their fingertips. DataFitting's built-in library includes a wide array of linear and nonlinear models from simple linear equations to high order polynomials. DataFitting has the following capabilities:
A 38-digit precision math emulator for properly fitting high order polynomials and rationals. A robust fitting capability for nonlinear fitting that effectively copes with outliers and a wide dynamic Y data range.
Once your data have been fit, DataFitting automatically sorts and plots the fitted equations by the statistical criteria of Standard Error. You can preview your graph and output publication-quality graphs in several different configurations. A residual graph as well as parameter output is generated for the selected fitted equation. Data, statistical and numeric summaries are also available from within the report-panel.  less

Although the 2009-2010 school year is barely off the ground, teens need to start thinking now about how to succeed on those ever-important math exams. Students are finding that the TI-Nspire graphing   more...calculator is one tool that helps them make it.

[NOTE: This video is only the first 18 minutes of the full lesson, please visit my web site to purchase complete version] Lesson consists of providing you with a Self-Tutorial on how to solve linear equations.   more...I discuss what is an Equation, Solution, Solution Set, Equivalent Equations, Identity, Contradictions, Conditional Equations, Linear Equations, the Standard Form of a Linear Equation. I show you how to actually SOLVE linear equations going step-by-step. I don't skip steps. I review some of the properties of Equality here too. I remind you to check the work done and how to solve linear equations using a calculator. At the end, you will know how to easily solve equations that look like:
2[y - (4y - 1)] = 5 - 9y
No word problems are done here. This is shown in DETAIL in Part 2 of the Lesson.  less

This lesson consists of providing you with a basic review of the formulas from geometry you will most likely encounter in algebra (and other math classes like trigonometry and calculus). This is NOT a   more...detailed, formal lesson.
Formulas and concepts covered include:
Angles (complementary & supplementary)
Triangles (perimeter and area)
Isosceles triangle
Equilateral triangle
Right triangle
The Pythagorean Theorem
Similar triangles
Perimeter and area formulas for Quadrilaterals (square, rectangle, parallelogram, trapezoid). Some diagonal formulas too, where applicable.
Circles (radius, diameter, circumference, area)
Cube (diagonal of face, diagonal of cube, surface area and volume)
