Oh ya, I remembered a little bit more about physics. You can take each direction to be a vector. In this case, x and y will be i (with that line showing its a vector) and j (with that line showing its a vector) respectively. Then it's 2i + 4j. You want k (with that line showing its a vector). Therefore k = sqrt(i^2 + j^2). I would find videos that demonstrate this, but I'm trying to finish a project for my data structs and algo course. Sorry, this doesn't explain much. I think YouTube videos would benefit you more than my half-ass explanations.

Thanks for your help
