If A= tan 15^(@) + cot 15^(@) , B= tan""22^(1^(@))/(2) + cot"" 22(1^(@))/(2) and C= sin 54^(@) - sin 18^(@) then the ascending order is

What is the value of (sin22(1^(@))/(2)+cos22(1^(@))/(2)) ?

prove that cot22(1)/(2)=sqrt(2)+1

Find the values (i) sin22(1^(0))/(2) (ii) cos22(1^(0))/(2)

sin^(-1)(-(sqrt(3))/(2))+cos^(-1)((sqrt(3))/(2))

(sin ^ (2) (22 (1) / (2)) ^ (@) + cos ^ (2) (22 (1) / (2)) ^ (@)) / (sin ^ (2) (44 (1) / (2)) ^ (@) + cos ^ (2) (44 (1) / (2)) ^ (@))

The value of cos22(1^(@))/(2) is

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))
