Learn what the limit of a function is and how to know if a limit does not exist. Review different types of limits and how to find limits...
The formal definition of a limit of a function in a general metric space is presented below. Let (X,dX) and (Y,dY) be metric spaces. Suppose E⊂X, f:E⟶Y is a function, and p is a limit point of E. Write f(x)→q as x→p, or limx→pf(x)=q. If there is a ...
The purpose of this article is to discuss the evaluation of the limit of a function in three ways. First the calculation is done, using L'H么pital's rule. The second method uses Taylor expansions of functions. The third method is based on graphical interpretation. Maple software provides ...

A group of mathematics students at undergraduate level at the National University of Lesotho was the sample for the study. Empirical data were collected using questionnaires and interviews. 关键词: epistemological obstacles function genetic decomposition limit understanding DOI: 10.1007/s10763-009-9168-...
I focus on applying the conceptual conflict idea to the concept of limit in the situation where approaches infinity. This strategy can be applied to the limit of a function when approaches a fixed number. 展开 关键词: Graphing Calculators Mathematics Mathematics Instruction Mathematical Concepts ...

Numbers and Mathematics Limits are the method by which thederivative, or rate of change, of a function is calculated, and they are used throughout analysis as a way of making approximations into exact quantities, as when the area inside a curved region is defined to be the limit of approxim...
The Limit of a Function at Infinity: We say that the limit of {eq}f(x) {/eq} as {eq}x {/eq} goes to infinity is {eq}L {/eq} if {eq}f(x) {/eq} gets arbitrarily close to {eq}L{/eq} as {eq}x {/eq} gets sufficiently large. We will use the ...
Instructors are constantly struggling to help students understand mathematical concepts as well as the relevance of mathematics to the real world. In calculus, students possess misconceptions of the limit concept. Pushing the Limit refers to a semester-long calculus class project that required students ...
