Active learning is the opposite of passive learning; it is learner-centered, not teacher-centered, and requires more than just listening; the active participation of each and every student is a necessary aspect in active learning. Students must be doing things and simultaneously think about the work done and the purpose behind it so that they ...
In mathematics, exponentiation, denoted b n, is an operation involving two numbers: the base, b, and the exponent or power, n. [1] When n is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, b n is the product of multiplying n bases: [1] = ⏟.
Learning by doing is a theory that places heavy emphasis on student engagement and is a hands-on, task-oriented, process to education. [1] The theory refers to the process in which students actively participate in more practical and imaginative ways of learning.
The plotted line represents the variation of instantaneous voltage (or current) with respect to time. This cycle repeats with a frequency that depends on the power system. In electrical engineering, three-phase electric power systems have at least three conductors carrying alternating voltages that are offset in time by one-third of the period ...
Power was born in Honiton, England on 12 February 1928. [1] He obtained his B.Sc and M.Sc in mathematics from University College London in 1948 and 1949 respectively. [1] He obtained his Ph.D under the supervision of John Currie Gunn at the University of Glasgow, for which he obtained the Kelvin Prize in 1951 (the prize recognizes the best physics thesis of the year). [1]
Every prime power (except powers of 2 greater than 4) has a primitive root; thus the multiplicative group of integers modulo p n (that is, the group of units of the ring Z/p n Z) is cyclic. [ 1 ] The number of elements of a finite field is always a prime power and conversely, every prime power occurs as the number of elements in some finite ...

In mathematics and statistics, sums of powers occur in a number of contexts: . Sums of squares arise in many contexts. For example, in geometry, the Pythagorean theorem involves the sum of two squares; in number theory, there are Legendre's three-square theorem and Jacobi's four-square theorem; and in statistics, the analysis of variance involves summing the squares of quantities.
