The value of (tan^(2)18^(@))(tan^(2)54^(@)) can be expressed as a rational number (p)/(q) in lowest form where p,q in N. Find the value of (p+q).

Prove that tan (13pi)/12=tan (pi)/12 and express tan (pi)/12 in the form of tan(A-B).

The expression (tan A)/(1- cot A) + ( cot A )/( 1- tan A) can be written as

If tanA=(1-cosB)/(sinB) , express tan 2A in terms of tan B
