1/b - 1/3

b-3

Lim b ----> 3

2. Relevant equations

3. The attempt at a solution

This is driving me nuts. I always end with 0 but thats not the answer.

I tried direct substitution and it didn't work.

I tried plugging in 2.999999999 but it gives a very small number devided by a very small number

I tried the conjugate and even deviding by the highest power altho thats for infinity.
