11.tan^(3)x

Evaluate int(tan x+tan^(3)x)/(1+tan^(3)x)dx

Show that tan 3 x=(3 tan x-tan ^(3) x)/(1-3 tan ^(2) x)

Prove that : tan 3x=(3tanx-tan^(3)x)/(1-3tan^(2)x)

tan^(3)x-3tan x=0

tan x+tan(x+(pi)/(3))+tan(x+2(pi)/(3))=3 prove that (3tan x-tan^(3)x)/(1-3tan^(2)x)=1

If tan x+tan(x+(pi)/(3))+tan(x+(2 pi)/(3))=3 then prove that (3tan x-tan^(3)x)/(1-3tan^(2)x)=1

lim_ (x rarr0) (tan ^ (3) x-tan x ^ (3)) / (x ^ (5)) equals

int cos ec^(6)xdx is equal to ................ 1) -cot x-(cot^(5)x)/(5)-(2cot^(3)x)/(3)+k 2) -(cot x)/(3)+(2cot^(5)x)/(5)+2cot^(-3)x+k 3) (tan^(3)x)/(3)-(tan x)/(5)+2tan^(3)x+k 4) (tan^(3)x)/(3)-(tan x)/(5)+3tan^(3)x+k

The value of lim_(x rarr(pi)/(3))((tan^(3)x-3*tan x)/(cos(x+(pi)/(6))))
