In this example, we are asked to determine the ratio of $\frac{\sin 18^{\circ}}{\cos 72^{\circ}} $. We know the sin18 value, in order to find the ratio first we have to calculate the Cos 72. We will start finding the value of Cos 72 by rewriting the cosine value in the ...

Buffon's needle is one such technique: If a needle of length ℓ is dropped n times on a surface on which parallel lines are drawn t units apart, and if x of those times it comes to rest crossing a line (x > 0), then one may approximate π based on the counts: displaystylepi...
