Thought-Process to Discover Knowledge

Welcome to **nub****trek**.

Books and other education websites provide "matter-of-fact" knowledge. Instead, nubtrek provides a thought-process to discover knowledge.

In each of the topic, the outline of the thought-process, for that topic, is provided for learners and educators.

Welcome to *the only place where the essence of "limit of a function" is explained*.

• `0/0` is called as indeterminate value -- meaning a function evaluating to `0/0` can take any value, it could be `0`, or `1`, or `7`, or `oo`, or undefined.

• other forms of indeterminate values are: `oo/oo`, `oo-oo`, `0^0`, `0xx oo`, or `oo^0`

Rigorous arithmetic calculations may result in `0/0`, but the expression may take some other value. The objective of limits is to find that value. The details explained are *revolutionary and provided nowhere else*.

Once that is explained, the topics in limits are covered. *(click for the list of lessons in this topic)*

Calculating Limits

Examining a function at an input value is made *simple and clear*. Based on the information, how to determine if the function is defined, continuous, or not defined. The following are covered.

• examining a function at an input value

• limit of a continuous function

• limit of a piecewise function

• limit of functions with abrupt change

• limit of functions that are not defined
