`(1 - tan^(2) 22 (1^(@))/(2))/(1 + tan^(2) 22 (1^(@))/(2))`= …….

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

Find the value tan(22(1^(@))/(2))

(tan 23^(@) + tan 22^(@))/(1- tan23^(@) * tan 22^(@))=

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)/(2) and A are not an odd multiple of (pi)/(2) then tan A= (2tan A)/(1-tan^(2)A) (2tan A)/(1+tan^(2)A) (2tan (A/2))/(1-tan^(2)(A/2))

tan22((1)/(2))^(@)=

Find the value tan(22(1)/(2)) .

((1+ tan 32^@)(1+tan 13^(@)))/((1+tan23^(@))(1+tan22^(@)))=

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