Watch the video for a how to on finding the domain and range:Ī Riemann integral is the “classic” integral you’re introduced to in introductory calculus classes. “we have AF the positive value of x equal to BA – BF, and for the negative value, BF must exceed BA, that is, F must be on the other side of A, as at F’, hence making AF’ equal to the absolute value of the negative root of the equation”.” What is an Absolute Value Function?

The term, as it relates to mathematics, was first found in 1950 in the elements of analytical geometry comprehending the doctrine of the conic sections, and the general theory of curves and surfaces of the second order by John Radford Young (1799-1885). HistoryĪccording to Math Boys, the word absolute comes from a variant of the word absolve and has a meaning close to free from conditions or restriction. (If you ever wondered why “two negatives equal a positive” in algebra, this last example, 4 – -2 helps to explain why!). For example the absolute difference of -5 and 4 is 9: For example:Ībsolute difference, |x-y,| is the distance of two numbers on the number line. For example, the absolute value of -10 is 10 and -1000 is 1000.Ībsolute value of a number is sometimes called the “modulus” of a number and is denoted by vertical bars on each side of the number.

You can easily figure out the magnitude of any number by removing the negative sign. The absolute value also refers to the magnitude of a number. The absolute value of -3 is 3, because it’s three spaces from zero on the number line.
