I have the feeling that an engineer should be more comfortable with math, than I'm felling I am right now. I also have a tendency toward learning math not required by the math classes I took, and was always leaning toward more fundamental way of doing engineering (math & physics.) Though I'm "fundamentalist" I feel much more comfortable with practical side of engineering, having no difficulty to learn different tools, methods etc. - while my math background seems shaky. I would like to be able to study math for engineering by myself (maybe even reading math papers in the future; distant one) and would like to know what should I learn first (take that I'm 1st year in university, although I'm not.)
What math should EE & CT engineer master and what should he be fond of?
