" Given "tan15^(@)=2-sqrt(3)," find "tan7(1)/(2)

If tan15^(@)=2-sqrt(3) , the value of tan15^(@)cot75^(@)+tan75^(@)cot15^(@) is

Prove that Tan15^(@)=2-sqrt(3)=Cot 75^@

If tan15^(@)=2-sqrt(3) then value of tan15^(@)cot75^(@)+tan75^(@)cot15^(@) is

Prove that (i) "cos " 15^(@) - " sin " 15^(@) = (1)/(sqrt(2)) (ii) " cot " 105^(@) - " tan " 105^(@) =2sqrt(3) (iii) (tan 69^(@) + tan 66^(@))/(1-tan 69^(@) tan 66^(@)) =-1

The value of tan^(-1)((sqrt(3))/(2))+tan^(-1)((1)/(sqrt(3))) is equal to a) tan^(-1)((5)/(sqrt(3))) b) tan^(-1)((2)/(sqrt(3))) c) tan^(-1)((1)/(2)) d) tan^(-1)((1)/(3sqrt(3)))

Prove that Cot105^(@)=-(2-sqrt(3))=-Tan15^(@)

Show that tan 15^@ = 2 - sqrt3

If tan 15^(@) = 2 - sqrt(3) , then show that 2 tan 1095^(@) + cot 975^(@) + tan (-195^@) = 4 - 2sqrt(3) .

The value of (1-tan^(2)15^(@))/(1+tan^(2)15^(@))=(A)1(B)sqrt(3) (C) (sqrt(3))/(2)(D)2
