lim(x→∞)[(x²+1)/(2x²+x-1)-(x+1)/(4x+3)]

3 Answers

solve this...

lim 1/x â†’ 0

The expr. can be rewritten as ....

(1 + (1/x)²)(2 + 1/x - (1/x)²) - (1 + 1/x)(4 + 3/x)

So the ultimate ans is probably .... 1/2 - 1/4 = 1/4

Hope my procedure is correct ..... somebody please correct if I'm wrong ....

oh ho...i did a silly silly mistake ...1/2-1/4=1/2...:P:P
