cot22(1^(@))/(2)=

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

If A + B = (pi)/(4) , show that (cot A - 1) (cot B - 1) = 2 and hence deduce that cot 22^((1^(0))/(2))=sqrt(2)+1.

A=tan 15^(0)+cot15^(0),B= tan 22(1^(0))/(2)+cot 22(1^(0))/(2) and C= sin 54^(0)-sin 18^(0) then the ascending order of A,B C is

cot7(1^@)/2-cot37(1^@)/2-cot52(1^@)/2+cot82(1^@)/2 =

"cot 7" (1^(0))/(2) - "cot 37" (1^(0))/(2) - "cot 52" (1^(0))/(2) + "cot 82" (1^(0))/(2)=
