    Programs Best upper division Math for an EE major

    So I just changed my major from Math to EE this semester and I really would like to continue taking some math. I have completed the entire Calc 1-3, LA, DEQ's, and a intro stats course. I only need 1 more course for a math minor. (intro proofs won't count for this though). My university doesn't...

    B Vector Math: Adding, Subtracting & Division

    As far as I know, vectors can only be added, subtracted, or “multiplied” by dot or cross product. Does this mean that you couldn’t divide f-> by a-> to get m using the vector form of Newton’s second law? This would require dividing a vector by a vector, which seems to not be allowed.

    B Remainder of polynomial division

    Is this true? If the remainder of f(x) / g(x) is a (where a is constant), then the remainder of (f(x))n / g(x) is an I don't know how to be sure whether it is correct or wrong. I just did several examples and it works. Thanks

    B What are multiplication and division?

    Hey, I have often times wondered what is multiplication? Repeated addition is OK but for some reason it doesn't satisfy me. For example: 2*2cm is linear because it scales 2cm on the same dimension but 2cm*3cm is not scaling, it spans 2 dimensions. It seems as if the flow of operation takes a 90...

    I Can Division by Zero Be Solved in Mathematics?

    First of all, I didn't know where to put this in general math or differential equations. Let's start with the basic, x/0 = α. Where α is every number and decimal number from -∞ to +∞, by rearranging, we get x = 0α, x= 0, therefore only 0/0 = α. Now, we can integrate this with graphs. Take the...
