((1+tan13^(@))(1+tan32^(@)))/((1+tan12^(@))(1+tan33^(@)))=

((1+tan33^(@))(1+tan12^(@)))/((1+tan18^(@))(1+tan27^(@)))=

The expression ((1+tan37^(@))(1+tan8^(@))(1+tan15^(@))(1+tan30^(@)))/((1+tan2^(@))(1+tan43^(@))) reduces to

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

The value of ((sqrt(3)+tan11^(@))(sqrt(3)+tan19^(@)))/((1+tan13^(@))(1+tan32^(@))) is equal to

The value of tan 31^(@) tan 32^(@)tan 33^(@)…tan 59^(@) is-

Value of (1+tan 13)(1+tan 32)+(1+tan 12)(1+tan 33) =

tan^(-1)(tan((-33 pi)/(7)))

Prove that tan12^(@)tan24^(@)tan48^(@)tan84^(@)=1
