1 + 1/4 + (1.3)/(4.8) + (1.3.5)/(4.8.12)+...... = _____
Expand (1-x/2)^(-1/2) using Maclaurin Series and set x=1 and see what happens.
m not getting the answer by dat way.....plz help
If you have done MacLaurin expansion, you should be able to expand the expression.
What answer did you get?
1/2^(1/2)
i got the same answer too
Oh, sorry, the expression I gave is not correct.
It should have read:
[1/(1-x/2)]^(-1/2)
which should expand to
1+1/4+1.3/(4.8)+1.3.5/(4.8.12)+...
Please disregard the previous correction.
The original expression IS correct, as it says:
(1-x/2)^(-1/2) [note the negative sign of the exponent]
=sqrt[1/(1-x/2)]
and should expand to:
1+1/4+1.3/(4.8)+1.3.5/(4.8.12)+...
