Are you preparing for a competitive exam and struggling to remember all the important formulas for math? Don't worry; we've got you covered. In this article, we'll provide you with a free PDF download of essential math formulas for competitive exams that you can use as a reference.

1. Algebraic Formulas

Algebra is a branch of mathematics that involves the study of symbols and the rules for manipulating them. It is an essential component of many competitive exams, such as the SAT, GRE, and GMAT. Here are some essential algebraic formulas that you should know:

• Binomial Theorem: (a+b)^n = Σ(nCr) a^(n-r) b^r
• Exponential Laws: a^m a^n = a^(m+n), a^m / a^n = a^(m-n), (a^m)^n = a^(mn)

1. Geometric Formulas

Geometry involves the study of shapes, sizes, and positions of objects. It is an essential component of many competitive exams, including the ACT, SAT, and GRE. Here are some essential geometric formulas that you should know:

• Pythagorean Theorem: a²+b²=c²
• Distance Formula: √(x2-x1)²+(y2-y1)²
• Circle Formula: (x-h)²+(y-k)²=r²

1. Trigonometric Formulas

Trigonometry involves the study of angles and their relationships with triangles. It is an essential component of many competitive exams, including the SAT, ACT, and GRE. Here are some essential trigonometric formulas that you should know:

• Sine Rule: sinA/a = sinB/b = sinC/c
• Cosine Rule: a² = b² + c² - 2bc cosA
• Tangent Rule: tanA = sinA/cosA

Mathematics is a crucial subject that requires continuous practice and learning. By mastering essential formulas and concepts, you can improve your performance in competitive exams and increase your chances of success. Use the free PDF download of essential math formulas provided in this article as a reference to help you prepare for your exams. All the Best!!
