It contains questions from many fields of mathematics; about 50% of the questions come from calculus (including pre-calculus topics, multivariate calculus, and differential equations), 25% come from algebra (including linear algebra, abstract algebra, and number theory), and 25% come from a broad variety of other topics typically encountered in ...

Changes to the GRE took effect on November 1, 2007, as ETS started to include new types of questions in the exam. The changes mostly centered on "fill in the blank" type answers for the mathematics section that requires the test-taker to fill in the blank directly, without being able to choose from a multiple choice list of answers.
The forms below normally assume the Cauchy principal value around a singularity in the value of C but this is in general, not necessary. For instance in ∫ 1 x d x = ln | x | + C {\displaystyle \int {1 \over x}\,dx=\ln \left|x\right|+C} there is a singularity at 0 and the antiderivative becomes infinite there.
The simple form is obtained from this by taking q 1 = q 2 = ... = q n = 2, which gives n + 1 objects. Taking q 1 = q 2 = ... = q n = r gives the more quantified version of the principle, namely: Let n and r be positive integers. If n(r - 1) + 1 objects are distributed into n boxes, then at least one of the boxes contains r or more of the ...
When an inline formula is long enough, it can be helpful to allow it to break across lines. Whether using LaTeX or templates, split the formula at each acceptable breakpoint into separate <math> tags or {} templates with any binary relations or operators and intermediate whitespace included at the trailing rather than leading end of a part.
The gradient of a function is obtained by raising the index of the differential , whose components are given by: =; =; =, = = The divergence of a vector field with components is
Mathematical notation is widely used in mathematics, science, and engineering for representing complex concepts and properties in a concise, unambiguous, and accurate way. For example, the physicist Albert Einstein 's formula E = m c 2 {\displaystyle E=mc^{2}} is the quantitative representation in mathematical notation of mass–energy ...
