`lim_(theta->0) (3tantheta-tan3theta)/(2theta^3)`

underset(theta to 0)"Lt" (3tantheta-tan 3 theta)/(2theta^(3))

lim_(theta rarr 0)(tan theta - sin theta)/(theta^(3))=

tantheta+tan2theta=tan3theta

If sqrt(3)sintheta-costheta=0 , then show that tan3theta=(3tantheta-tan^(3)theta)/(1-3tan^(3)theta)

sin^(3)theta = tan2theta + tantheta

If tan theta+tan(60^(@)+theta)+tan(120^(@)+theta)=3, Prove that: (3tantheta-tan^(3)theta)/(1-3tan^(2)theta)=1

If tan theta+tan(60^(@)+theta)+tan(120^(@)+theta)=3, Prove that: (3tantheta-tan^(3)theta)/(1-3tan^(2)theta)=1

lim_(x rarr0)(sin^(3)theta*tan^(3)theta)/(theta^(6))

Prove the following : tan4theta = (4tantheta-4tan^3theta)/(1-6tan^2theta+tan^4theta)

lim_(theta rarr 0) (4 theta(tan theta-sin theta))/(1-cos 2 theta)^2 is
