Algebra: Solving Linear Equations - Part 1: The Basics

Thursday, June 18th, 2009

[NOTE: This video is only the first 18 minutes of the full lesson, please visit my website to purchase complete version] Lesson consists of providing you with a Self-Tutorial on how to solve linear equations. Tutor discusses 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.

Basic Math: Lesson 6 - Introduction to Fractions

Sunday, May 10th, 2009

An informal introduction to why we need to learn about fractions.

Lesson 6 consists of providing you with a Self-Tutorial on all about fractions. This lesson is different from the previous ones in that the use of printed Notes is integrated with the Video (other Notes may be used independently of the videos). This lesson is VERY detailed and covers the necessary areas to help students review the many aspects of fractions and fraction conversions. I also show you how to perform all the many different fraction operations and conversions using the TI-84+ Graphing Calculator.

Algebra: Formulas From Geometry

Thursday, May 7th, 2009

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 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)
Rectangular box [or Rectangular Parallelepiped] (diagonal of box, surface area and volume)
Prisms (Volume)
Pyramids (Volume)
Cone (slant height, lateral surface area, total surface area, volume)
Cylinder (lateral surface area, total surface area, volume)
Sphere (surface area and volume)
