A necessary consideration in the development or expansion of courses incorporating techniques such as geographic information systems (GIS) is the establishment of the infrastructure to support such instruction. Planning for the practical application of knowledge involves the determination of hardware, software, data and personnel needs.
Continuity: the tendency to perceive things as simply as possible with a continuous pattern rather than with a complex, broken-up pattern o Contiguity: the tendency to perceive 2 things that happen close together in time as being related Rods and cones, which one is less or more light/color sensitive?
Otherwise, a function is said to be a discontinuous function. A continuous function with a continuous inverse function is called a homeomorphism. Continuity of functions is one of the core concepts of topology, which is treated in full generality below.iven a sequence. of functions such that the limit. exists for all x in I, the resulting function f (x) is referred to as the pointwise limit of the sequence of functions (f n) nâN. The pointwise limit function need not be continuous, even if all functions f n are continuous, as the animation at the right shows.
