Hi all you opto guys and gals. I am a new member here on SDN. I am thinking about opt. school, but one of the things holding me back is the aspect of math. I the type of guy who is great at memorizing things, but my fluid capabilities (e.g. math) are not as strong as I would like them to be. I am wondering how much calc. and math you guys utilize in your classes, e.g. optics classes... Thanks so much in advance.
