Prove that : (sin^(4)theta- cos^(4) theta+ 1) "cosec"^(2)theta=2

Prove that : (sin^(4)theta- cos^(4) theta+ 1) "cosec"^(2)theta=2

if sin A=(1)/(4) then cosec^(-1)4

Prove that sin^(4)A"cosec"^(2)A+cos^(4)Asec^(2)A=1

Expression (sin^(4) x - cos^(4)x +1)"cosec"^(2)x is equal to:

Prove that sin^2(pi/4) + cos^2(pi/4) +cosec^2(pi/6) = 5

What is the value of (sin^(4)theta-cos^(4)theta+1)"cosec"^(2)theta ?

cos[2 sin^(-1) 3/4 + cos^(-1)3/4]

If sin^(-1)(π/5)+cosec^(-1)(5/4) = 5/2 .

Prove that: [1/(sec^(2)A-cos^(2)A)+1/("cosec"^(2)A-sin^(2)A)].sin^(2)A.cos^(2)A=(1-sin^(2)Acos^(2)A)/(2+sin^(2)Acos^(2)A)
