Quadratic Equations 與 Calcu-Logarithm 使用情況與統計
A power learning aid combining Practice, Coaching Calculators and Guides to help students master the solving of quadratic equations.
Coaching Calculators solve quadratic equations by :
- completing the square
- quadratic formula
- factoring
Students learn quickly by working with the calculator and seeing each step of the process in detail.
Completing the square for example:
- Dividing by coefficient of x²
- Taking constant term to right hand side
- Completing the square
- Taking the square root of both sides
- Simplifying and solving
Practice includes examples from basic such as x² + 3x + 2 = 0 to equations with rational (fractional) coefficients.
Guides have a comprehensive set of examples

Calcu-Logarithm performs calculations and helps user understand logarithms on advanced level:
1. Solves equation "y = log_a(x)” for “y”, “x”, and “a”, with relevant graphs.
2. Explains and illustrates how to compute log_e (x) from Taylor series.
3. Explains and illustrates how to compute log_10 (x) digit by digit (based on M.Goldberg algorithm).
4. Explains and provides proof of log_e definition as the integral of x inverse.
5. Simplifies logarithmic expressions and solves logarithmic equations with polynomials of up to 20th degree.
6. Includes virtual slide rule for multiplication and division.
7. Calculates, explains, and graphs logarithms of complex numbers.
