Hi, I have been working on this for a little while and think I am approaching it incorrectly. If someone can help, I'd really appreciate it. This is for a basic introductory calculus based Physics class that I am in.(adsbygoogle = window.adsbygoogle || []).push({});

1. Mathematically demonstrate the following equation with no numerical examples

2. [tex] \frac{1}{f_{c}} = \frac{1}{f_{1}} + \frac{1}{f_{2}} [/tex] - This is the equation for the focal distance of two touching thin lenses.

3. I have tried using the lens equation for the first and second lens, and solving for a distance of zero between them, but i can't figure out how to solve for where the image from the first lens would be, and therefore how the second lens would act on it

Thanks Very Much.
