The replacement theorem shows that every basis of a space named for this word has the same size. Some of these structures are linearly dependent if one of them can be written as a combination of the others. Calculus on [this]-valued functions uses the operators "div" and "curl." A type of graphics named for this word can be (*) scaled indefinitely, unlike raster graphics. In epidemiology, this is 
The replacement theorem shows that every basis of a space named for this word has the same size. Some of these structures are linearly dependent if one of them can be written as a combination of the others. Calculus on [this]-valued functions uses the operators "div" and "curl." A type of graphics named for this word can be (*) scaled indefinitely, unlike raster graphics. In epidemiology, this is the term for pathogen-carrying organism, such as a mosquito. They can be multiplied by scalars, and the parallelogram law governs their addition. For 10 points, name these structures which are often depicted on the Cartesian plane as an arrow with magnitude and direction.
