Step-by-step explanation:
It has something to do with the<em> </em><u><em>Weierstrass substitution</em></u>, where we have
First, consider the double angle formula for tangent:
Therefore,
Once the double angle identity for sine is
we know , but sure, we can derive this formula considering the double angle identity
Recall
Thus,
Similarly for cosine, consider the double angle identity
Thus,
Hence, we showed
