cos^(2)52(10)/(2)-sin^(2)22(10)/(2)

If cos^(2)52(1)/(2)-sin^(2)22(1)/(2) = (alpha-sqrt(beta))/(gamma sqrt(delta)) then value of (alpha+beta)/(gamma+delta)

Find the value of cos^(2)52(1^@)/(2) - sin^(2)22 (1^@)/2

Find the value of cos^(2)112^((1^(0))/(2))-sin^(2)52^((1^(0))/(2)) cos^(2)52^((1^(0))/(2))-sin^(2)22^((1^(0))/(2))

Prove that sin^(2)52 1/2-sin^(2)22 1/2 .

sin ^ (2) 52 (1) / (2) -sin ^ (2) 22 (1) / (2) =

the value of (tan^(2)(10)*sin^(2)(10))/(tan^(2)(10)-sin^(2)(10))

(sin((pi)/(10))+sin(13(pi)/(10)))(cos^(2)((pi)/(6))-cos^(2)((pi)/(10))) is equal to

cos ^ (2) 52 ((1) / (2)) ^ (@) - sin ^ (2) 22 ((1) / (2)) ^ (@) =
