Here are some common math formulas that cover various mathematical concepts:

1. Geometry Formulas:
• Area of a Rectangle: A = length × width
• Area of a Triangle: A = 1/2 × base × height
• Area of a Circle: A = πr² (where r is the radius)
• Circumference of a Circle: C = 2πr
• Volume of a Cube: V = side³
• Volume of a Cylinder: V = πr²h (where r is the base radius and h is the height)
2. Algebra Formulas:
• Quadratic Formula: x = (-b ± √(b² - 4ac)) / (2a)
• Slope of a Line: m = (y₂ - y₁) / (x₂ - x₁)
• Distance Formula: d = √((x₂ - x₁)² + (y₂ - y₁)²)
• Binomial Theorem: (a + b)ⁿ = Σ [C(n, k) * a^(n-k) * b^k], where Σ is the sum from k = 0 to n, and C(n, k) is the binomial coefficient.
3. Trigonometry Formulas:
• Sine Rule: a/sin(A) = b/sin(B) = c/sin(C)
• Cosine Rule: a² = b² + c² - 2bc * cos(A)
• Tangent Identity: tan(θ) = sin(θ) / cos(θ)
4. Calculus Formulas:
• Derivative of a Function (f'(x)): It depends on the function and can involve rules like the power rule, product rule, and chain rule.
• Integral of a Function (∫f(x) dx): It also depends on the function and involves techniques like integration by parts, substitution, etc.
5. Probability and Statistics Formulas:
• Mean (Average): μ = Σx / N (where Σx is the sum of all values and N is the number of values)
• Standard Deviation: σ = √[Σ(xi - μ)² / N] (where xi is each data point)
• Probability of an Event: P(A) = (Number of favorable outcomes) / (Total number of possible outcomes)
6. Logarithmic and Exponential Formulas:
• Logarithm Rules: Log(a * b) = Log(a) + Log(b), Log(a / b) = Log(a) - Log(b), Log(a^n) = n * Log(a)
• Exponential Growth: A = P(1 + r/n)^(nt), where A is the future value, P is the principal amount, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years.

These are just a few examples of mathematical formulas. The specific formulas you need may vary depending on the math topic you're studying or the problem you're trying to solve. If you have a specific math concept or formula you'd like to know more about, please feel free to ask!
