I need to derive the formula for this "film projection wheel" (it just has four holes in the center). Ive looked all over google AND Hyperphysics but I havent found a site that shows how to derive the formulas.(adsbygoogle = window.adsbygoogle || []).push({});

Please can someone help me (my phsyics teacher is a dick: hes been missing for 3/4 of the semester).
