Algebra Formulas
+(a−b)² = a² − 2ab + b²
a² − b² = (a+b)(a−b)
x = (−b ± √(b²−4ac)) / 2a
Geometry Formulas
+Area of rectangle = length × width
Perimeter of rectangle = 2(l + w)
Volume of cuboid = l × w × h
Trigonometry Formulas
+cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
sin²θ + cos²θ = 1
Circle Formulas
+Area = πr²
Arc length = (θ/360) × 2πr
Percentage Formulas
+Percentage change = (new − old) / old × 100
