Solution

Mirror formula is $\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$
Lens formula is $\frac{1}{v} - \frac{1}{u} = \frac{1}{f}$
Power = $\frac{1}{f}$
Magnification = $\frac{h_{i}}{h_{o}}$

If $| u | < 1, | v | < 1$ , and $z = \frac{u - v}{1 + ¯ u v}$ , then least value of $| z |$ is

\frac{1}{u} + \frac{1}{v} = \frac{1}{f}

\frac{1}{v} - \frac{1}{u} = \frac{1}{f}
