Find tan 15^(@) and hence show that tan 15^(@) + cot 15^(@) =4 .

Prove that (i) " sin " 75^(@) =((sqrt(6)+sqrt(2)))/(4) (ii) (cos 135^(@) -cos 120^(@))/(cos 135^(@) +cos 120^(@)) =(3 -2sqrt(2)) (iii) " tan " 15^(@) +" cot " 15^(@) =4

A quadratic equation whose roots are tan15^(@) and cot15^(@) is

If A=sin15^(0)+cos15^(@),B=tan15^(@)+cot15^(@),C=tan22(1^(@))/(2)-cot22(1^(@))/(2) thenthe descending order is

If A= tan 15^(@) + cot 15^(@) , B= tan""22^(1^(@))/(2) + cot"" 22(1^(@))/(2) and C= sin 54^(@) - sin 18^(@) then the ascending order is

if cot15^(@)=m, " then find " (cot195^(@)+cot345^(@))/(tan15^(@)-cot105^(@))
