i think this is a good que.....

1+ tan 1 = 1 + tan(45-44)
= 1 + 1-tan44
---------
1+ tan44

= 2/(1+ tan 44)

and it will get canceled out with (1+ tan 44) leaving a remainder of 2...

in this way u will finally cancel out (1+ tan 22) and (1+ tan 23)

leaving with u:

2^22 *(1+ tan 45)

finally u get:

2^23

hope u got it now.......

this word is so small that it is a foolishness to hate anyone.
so, we love all.
