Math Formulas Cheat Sheet (Daily Student Use)
Algebra: (a + b)² = a² + 2ab + b²
Algebra: (a - b)² = a² - 2ab + b²
Difference of Squares: a² - b² = (a - b)(a + b)
Quadratic Formula: x = [-b ± √(b² - 4ac)] / 2a
Area of Circle: A = πr² (Where r = radius)
Circumference: C = 2πr
Trigonometry: sin²θ + cos²θ = 1
Trigonometry: tanθ = sinθ / cosθ
Pythagoras Theorem: a² + b² = c² (Hypotenuse)
Volume of Cylinder: V = πr²h
Logarithm: log(ab) = log(a) + log(b)
