Amount and Quality of Light. The lighting in classrooms is extremely important to learning. One of the major causes of stress in schools is over-lighting. Fluorescent lights are the worst and their constant flickering is distracting and can cause headaches as well as reduce the amount of serotonin in the brain.
The sum of the terms of the geometric sequence is known as a geometric series; Sn = ar+ ar2 + ar3 + â¯ + arn = âi=1ân ari. The sum of the geometric series can be calculated using the following formula. Sn = a(1-rn)/(1-r); where a is the initial term and r is the ratio. If the ratio, r â¤ 1, the series converges.
Not to be confused with symbolic execution. In computational mathematics, computer algebra, also called symbolic computation or algebraic computation, is a scientific area that refers to the study and development of algorithms and software for manipulating mathematical expressions and other mathematical objects.
