cot7(1)/(2)

4cos36^(@)+cot(7(1)/(2))^(@)=

If cos36^(@)+cot(7(1)/(2)@)=sqrt(n_(1))+sqrt(n_(2))+sqrt(n_(3))+sqrt(n_(1))+sqrt(n_(5))+sqrt(n_(6)) then the value of sum_(i=1)^(6)n_(i)^(2) must be

cot 7 (1)/(2)^(circ)=

cot(7((1)/(2))^(@)=sqrt(p)+sqrt(q)+sqrt(r)+sqrt(s)

The value of cot7(1^0)/2+tan67(1^(@))/2-cot67(1^(@))/2-tan7(1^0)/2 is

The number of points of intersection of the curves represented by arg(z-2-7i)=cot^(-1)(2) and arg ((z-5i)/(z+2-i))=pm pi/2

The number of points of intersection of the curves represented by arg(z-2-7i)=cot^(-1)(2) and arg ((z-5i)/(z+2-i))=pm pi/2

4 cos 36^(circ)+cot (7 (1)/(2))^(circ)=

Show that cot 7(1^@/2)=2+sqrt2+sqrt3+sqrt6
