Question

What is lim (1/b-1/2)/(b-2)?
b->2

Answer 1

3 squared

Answer 2

how?

Answer 3

-(1/4)
\[\lim_{b \rightarrow 2}\left( 1/b - 1/2 \right)/\left( b-2 \right)=\]
\[\lim_{b \rightarrow 2}(\left( 2-b \right)/\left( 2b \right))/\left[ b-2 \right]\]
\[\lim_{b \rightarrow 2}\left( 2-b \right)/\left( 2b*\left( b-2 \right) \right)\]
\[\lim_{b \rightarrow 2} -1/(2b) =-1/4\]
