Page 1: Essential Mathematical Formulas and Geometric Principles
The first page presents fundamental mathematical formulas covering financial calculations and geometric principles. The simple interest formula A = P + PRT is thoroughly explained with its components clearly defined.
Definition: Simple Interest Formula components are defined as A Amountafteryears, P Principal, R Annualinterestrate, and T Numberofyears.
The page includes comprehensive geometric formulas for various shapes including triangles, squares, rectangles, trapezoids, and circles.
Highlight: The interior angles of a triangle always sum to 180 degrees, demonstrated with an equilateral triangle example of 60° + 60° + 60°.
Example: Area calculations are provided for multiple shapes:
- Square: Area = s²
- Rectangle: Area = l × w
- Triangle: Area = ½bh
- Trapezoid: Area = ½hb1+b2
Vocabulary: Pi π is defined as either 3.14 or 22/7, essential for circular calculations.
