Algebra Formulas

The Quadratic Formula: A solution to the quadratic equation ax^2 + bx + c = 0 is given by the formula x = (-b ± √(b^2 - 4ac)) / (2a). This formula is a powerful tool in finding the roots of any quadratic equation.

The Binomial Theorem: Describes the algebraic expansion of powers of a binomial. According to the theorem, (a + b)^n = Σ [n! / (k!(n - k)!) ] a^(n-k) b^k, where Σ denotes the sum over all values of k from 0 to n.

Geometry Formulas

Area and Perimeter:

• Square: Area = side^2, Perimeter = 4 × side
• Rectangle: Area = length × width, Perimeter = 2 × (length + width)
• Circle: Area = πr^2, Circumference = 2πr

Volume Formulas:

• Sphere: Volume = (4/3)πr^3
• Cylinder: Volume = πr^2h
• Cone: Volume = (1/3)πr^2h

Trigonometry Formulas

Basic Ratios: The sine, cosine, and tangent of an angle θ are fundamental in trigonometry, relating the angles of a triangle to the lengths of its sides.

Sine and Cosine Rules: Essential for solving any triangle when certain measures are known. The Sine Rule: a/sin(A) = b/sin(B) = c/sin(C), and the Cosine Rule: c^2 = a^2 + b^2 - 2ab cos(C).

Calculus Formulas

Derivatives: The derivative of a function represents an infinitesimal change in the function with respect to one of its variables. Common formulas include d/dx(x^n) = nx^(n-1).

Integrals: Integration is the inverse process of differentiation, useful in calculating areas under curves, among other things. The Fundamental Theorem of Calculus connects differentiation and integration.

Statistics Formulas

Mean, Median, Mode: These measures of central tendency are fundamental in data analysis. Mean is the average, median is the middle value when data is ordered, and mode is the most frequent value.

Standard Deviation: A measure of the amount of variation or dispersion in a set of values. A low standard deviation means the values are close to the mean, while a high standard deviation indicates the values are spread out over a wider range.

Conclusion

Understanding and applying these fundamental math formulas can dramatically improve problem-solving skills and mathematical fluency. While memorization can be helpful, true mastery comes from understanding the concepts behind the formulas and practicing their application in a variety of contexts. Whether you're a student facing exams or a professional encountering mathematical challenges, this standard formula sheet is your go-to resource for success.
