Now for |x|<1, we have
By using the identity and equating coefficients we can solve several problems of sequence and binomial.

From a point M inside an equilateral triangle ABC perpendiculars MP, MQ, MR are
dropped to sides BC, CA, AB respectively.
By pythagores theorem
A triangle cuts off from the circum circle three circular segments.
The largest altitudes of the segments with in radius and circum radius
of the triangle has relation
Where K, L, M are the length of the largest altitudes and R, r have usual meaning.
Let O be the circum centre of the triangle. Let D be the midpoint of BC
