AN APTITUDE IS A COMPONENT OF A COMPETENCY TO DO A CERTAIN KIND OF WORK AT A CERTAIN LEVEL, WHICH CAN ALSO BE CONSIDERED “TALENT”. APTITUDES MAY BE PHYSICAL OR MENTAL. APTITUDE IS DEVELOPEDKNOWLEDGE, UNDERSTANDING, LEARNED OR ACQUIRED ABILITIES (SKILLS) ORATTITUDE. THE INNATE NATURE OF APTITUDE IS IN CONTRAST TO ACHIEVEMENT, WHICH REPRESENTS KNOWLEDGE OR ABILITY THAT IS GAINED THROUGH LEARNING.
EXAMPLE: NUMBER OF WORKER COMPLETE THE TASK IN 10 DAYS. IF 5 WORKER NOT REPORTED FOR WORK .WORK CAN BE COMPLETED IN 12 DAYS .FIND HOW MANY WORKERS CAN COMPLETE THE TASK IN 10 DAYS.
To answer these type of Questions is easy. So start Solving These sort of problems.
The mathematical formulations of quantum mechanics are thosemathematical formalisms that permit a rigorous description of quantum mechanics. Such are distinguished from mathematical formalisms for theories developed prior to the early 1900s by the use of abstract mathematical structures, such as infinite-dimensional Hilbert spaces and operators on these spaces. Many of these structures are drawn from functional analysis, a research area within pure mathematics that was influenced in part by the needs of quantum mechanics. In brief, values of physical observables such asenergy and momentum were no longer considered as values of functions onphase space, but as eigenvalues; more precisely: as spectral values (point spectrum plus absolute continuous plus singular continuous spectrum) of linear operators in Hilbert space.
