[SOUND] Hi, welcome to the second
week of the calculus course. Recently we've covered various basic
concepts for functions, such as domain, support, range, co-domain, and basic
transitions of elementary functions graph. Also we've speaked about functions
of natural domain of sequences and its limits. Now it's essential for us to turn over to the case of real
domain functions or functions in general. Also, we are going to speak
about not only its limits as a comparison of a sequence
in the given point and the idea of multivariate functions,
or just administering another degree of freedom into
the system seen in the following video. [SOUND]
