Plane forms Point direction form: \( a(x-x_1) + b(y-y_1) + c(z-z_1) = 0 \) where \(P(x_1, y_1, z_1)\) lies in the plane, and the direction (a,b,c) is normal to the plane. General form: \( Ax + By + Cz + D = 0 \) where direction (A,B,C) is normal to the plane. Intercept form: \( \frac{x}{a} + \frac{y}{b} + […]

## Lines in Three Dimensions

Line forms Point direction form: \( \frac{x-x_1}{a} = \frac{y – y_1}{b} = \frac{z-z_1}{c} \) Two point form: \( \frac{x-x_1}{x_2-x_1} = \frac{y – y_1}{y_2-y_1} = \frac{z-z_1}{z_2-z_1} \) Parametric form: \( \begin{aligned} x &= x_1 +t\,\cos \alpha \\ y &= y_1 +t\,\cos \beta \\ z &= z_1 +t\,\cos \gamma \end{aligned} \) Distance between two lines in 3 dimensions The […]

## Integrated Algebra For Beginners

Integrated algebra introduces us with the basic concepts of trigonometry and calculus. It is generally made up of variables, expressions, operations and equations. Variables Variables can help the students to make references to numbers that are unknown. For instance x or y. Variables are always used in expressions. Expressions Expressions are set of the symbols […]
