How would I prove that "tan (x+1) 2 = (1+sin(2x))/cos 2 x" ?

How would I prove that "tan(x+1)2 = (1+sin(2x))/cos2x" ?

 

It is not clear what you want me to prove....

 

\(tan(x+1)^2 = \frac{1+sin(2x)}{cos2x}\\ or\\ tan(x+1)^2 = \frac{1+sin(2x)}{cos^2x}\\\)

 

The symbol for power on the net is ^

ex       3^2=9

 

Could you please rewrite your question clearly.
