Determining limits from a graph
WebWhat is a limit? Calculus involves a major shift in perspective and one of the first shifts happens as you start learning limits. ... As you continue to study limits, the plan is to develop ways to find limits without using the graph, but being able to find a limit this way can give you a much better understanding of exactly what a limit is ... WebThis is the graph of y = x / sin (x). Notice that there's a hole at x = 0 because the function is undefined there. In this example, the limit appears to be 1 1 because that's what the y y -values seem to be approaching as our x x -values get closer and closer to 0 0. It doesn't matter that the function is undefined at x=0 x = 0. Learn for free about math, art, computer programming, economics, physics, …
