Prove that 1/Sin2A + Cos4A/Sin4A= CotA - Cosec4A| Trigonometry
hllo guys welcome to the new video. guys in this video we will discuss about a very fantastic topic that is trigonometric question.
this is a very tuff question so students used to say that this is very hard topic but believe me this is very easy to understand.

so watch the full video and get clear your doubt.

thank you
