If `cot A tan ((n- 1)A)`, where `n in N`, then a value of A can be

If cot A= tan (n-1) A, show that one value of A is pi/(2n) .

If prod_(k=1)^(29)(sqrt(3)+tan k^(@))=2^(n) where n in N hen the value of n is equal to

If the value of cot(11(1)/(4^(@)))+tan(112(1)/(2^(@)))-cot(112(1)/(2^(@)))-tan(11(1)/(4^(@)))=sqrt(n) where n in N then find the value of n

If the value of cot(11 1/4^@)+tan(112 1/2^@)-cot(112 1/2^@)-tan(11 1/4^@)=sqrtn where n in N then find the value of n

If cot A ="tan"(n-1)A ,show that one value of A is (pi)/(2n)

If cot^(-1)(n/(pi))>(pi)/6, n in N , then the maximum value of n is :
