Limits at Positive Infinity with Radicals
In this tutorial we shall discuss an example related to the limit at positive infinity with the radial form of a function, i.e. .
Let us consider an example:
By rationalizing, we have
We divide the numerator and denominator of the fraction by . Since we are considering only negative values of
and
for
, using these values we have
Using the relation , we have
By applying limits, we have
