Show that `tan 75^(@)+cot 75^(@)=4`.

tan75^(@)

tan75^(@)+cot75^(@)=

Show that tan75^(@)+cot75^(0)=4

Prove that, tan 75^(@) - cot 75^(@) = 4 sin 60^(@)

Show that tan 75^(@) = (sqrt3) +(1 )/( sqrt3 -1) = 2 + sqrt3. Hence deduce that tan 75^(@) - cot 75^(@) = 4 sin 60^(@).

Show that tan 75^0 + cot 75^0 = 4

Prove that: tan75^(@)+cot75^(0)=4

Prove that: "tan"A+cotA=2"cosec" 2A and deduce that "tan" 75^(@)+cot 75^(@)=4 .

Tan75^(@) - Cot75^(@) =
