In the limit
we're interested in the value that converges to as
gets closer to
. So in fact
.
In the given example, is factorized to reveal a common factor of
in the numerator and denominator. We have
if
, so
so we can simplify
and *remove* the discontinuity.
Then
Answer:
Step-by-step explanation:
we know that
The incenter of a triangle is the meeting point of the three angle bisectors of a triangle.
so
we have
-----> given problem
so
Remember that
In a triangle the sum of the internal angles must be equal to
so
In the right triangle OQB
substitute
