9) A cone height 2 m and raduis 1 m, Is placed inside a bigger cone of 2 m raduis, such that their axis are common and vertes of smaller cone is at the center of the base of ...

wrong post.

ans b

assume triangle third angle -> 0

the expression reduces to

2 side^2/side^2 -> 2 hence answer (b)

1+ 1/9+ 1/25 ........... + 1/4( 1+ 1/4 +1/9.........)

so S= S/4+ N

3/4S = N

S= 4/3 N

so (e)

The answer is not C for the changed question. Please be more careful in selecting the right option.

Did you pay heed to the open bracket in option (c)?

The roots of sinx/x are n*pi,viz +/- pi.+/-2pi and so on.

Hence,sinx/x = (1-x/pi) (1+x/pi) (1-x/2pi) (1+x/2pi) (1-x/3pi) (1+x/3pi)...

Coeff of x^2 here= -(1/pi^2 + 1/4pi^2 + 1/9pi^2 + ......
