2) What's a mathematical induction?

Explanation

Mathematical induction is a proof technique used to prove statements about natural numbers or other well-ordered sets. It involves two steps: the base case, where the statement is proven to hold for a specific value, and the induction step, where it is proven that if the statement holds for one value, it also holds for the next value. By using this technique, mathematical statements can be proven to be true for an infinite number of cases.

4) What's the other name for an empty sum?

Explanation

A nullary sum refers to an empty sum, where there are no elements to add together. It is called nullary because it represents the absence of any operands or values. In this case, the sum is non-existent or voided because there are no numbers to sum up. Therefore, the correct answer is "Nullary sum."

Submit
5) What's a Riemann sum?

Explanation

A Riemann sum is a method used to approximate the value of an integral by dividing the interval into smaller subintervals and evaluating the function at specific points within each subinterval. The sum of these evaluations multiplied by the width of each subinterval gives an approximation of the integral. Therefore, the correct answer is "It's an approximation of an integral by a finite sum."

6) What are the natural numbers?

Explanation

The natural numbers are a set of numbers that are used for counting and ordering. They include all positive integers starting from 1 and do not include any fractions, decimals, or negative numbers. Counting refers to the process of determining the quantity of objects or entities, while ordering refers to arranging the numbers in a specific sequence or pattern. Therefore, the natural numbers are specifically used for both counting and ordering purposes.

7) What's an ellipsis?

Explanation

An ellipsis is a series of dots that is used to indicate an intentional omission of a word. It is commonly used in writing to show that something has been left out or to create a pause in speech. The series of dots is a visual representation of the missing word or words, allowing the reader or listener to understand that something has been intentionally omitted.

8) What's a finite difference?

Explanation

A finite difference is a mathematical expression that represents the difference between two values of a function, where the values are taken at different points in the domain. In this case, the correct answer is "It is a mathematical expression of the form f(x+b)-f(x+a)". This expression represents the difference between the function values at two points, x+b and x+a, respectively. By subtracting the function value at x+a from the function value at x+b, we obtain the finite difference.

9) What's a measure in mathematics?

Explanation

A measure in mathematics is a systematic way to assign a number to a suitable subset of a given set. This means that a measure provides a consistent and structured method for assigning numerical values to specific subsets of a set. It allows for the quantification and comparison of different subsets within a set, enabling mathematical analysis and reasoning.

10) What's the definite of an image in mathematics?

Explanation

The definition of an image in mathematics is a subset of the function's codomain that is obtained by mapping elements from a subset of its domain to the codomain.
