`(2 tan 22(1)/(2^(@)))/(1-tan^(2) 22(1)/(2)^(@))` बराबर है

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

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

A quadratic equation whose roots are tan22(1)/(2^(@)) and cot22(1)/(2^(@)) is

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

The value of cot22(1)/(2)-tan22(1)/(2) is

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

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

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