x^(tan x)

If f(x)=sin(tan x),g(x)=tan(sin x), then

Prove that tan13x = tan 4x + tan 9x + tan 4x tan 9x tan 13x

If tan (x-A)tan (x-B)+tan (x-B)tan (x-C)+tan(x-C)tan (x-A)=1 and A,B and C are the angles of triangle ABC then find x

If tan (x-A)tan (x-B)+tan (x-B)tan (x-C)+tan(x-C)tan (x-A)=1 and A,B and C are the angles of triangle ABC then find x

(tan(x+y)-tan x)/(1+tan(x+y)tan x)=tan y

(tan(x+y)-tan x)/(1+tan(x+y)tan x)=tan y

Prove that: (i) tan 8x-tan6x-tan2x=tan8x tan6x tan2x

tan8x-tan5x-tan3x=m tan8x tan5x tan3x then m

"tan"|x| = |"tan" x| , if
