Answer :

Here we need to find the value of given equation


As sec θ = cosec (90–θ))


sec2 54 = cosec2 36 …(1)


As, tan θ = cot (90–θ)


tan2 57 = cot2 33) …(2)


As, sec θ = cosec (90–θ)


sec2 52 = cosec2 38 ….(3)


Substituting (1) and (2) and (3) in given equation we can rewrite it as







The value of given equation is
