" 3."tan22(1^(@))/(2)

Find the value tan(22(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 alpha+beta=45^(@) , show that : (1+tanalpha)(1+tanbeta)=2. Hence, find the value of tan(22(1^(@))/(2)) .

Find the value of (1-tan^(2)22(1^(@))/(2))/(1+tan^(2)22(1^(@))/(2)) .

Evaluate : (2 tan 22 (1^(@))/( 2 ))/(1 - tan ^(2) 22 (1^(@))/( 2))

If A=sin15^(0)+cos15^(@),B=tan15^(@)+cot15^(@),C=tan22(1^(@))/(2)-cot22(1^(@))/(2) thenthe descending order is

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
