Question

Super proof :
_____________
Prove that :

Answer 1

\[Tan3\Theta=(3\tan \Theta-\tan ^{3}\Theta) \div(1-3\tan ^{2}\Theta)\]

Answer 2

\[\tan(x+y)=\frac{tanx+tany}{1-tanxtany}\]
x=y=theta
\[\tan(2 \theta)=\frac{2\tan \theta}{1-\tan^2 \theta}\]
7ot x=2 theta y=theta
\[\huge{\tan(3 \theta)=\frac{\frac{2\tan \theta}{(1-\tan^2 \theta+\tan \theta)}}{\frac{1-2\tan^2 \theta}{1-\tan^2 \theta}}}\]simpligy lol

Answer 3

simplify*
