Document Summary
11. 1 functions and several variables notes: sterling. Provide a generalization to each of the key terms listed in this section. When it comes to studying functions that have 2 or more variables, then there are 4 di erent points of views you can deal with. The algebraic point of view is when you are studying functions by using explicit formulas. The numerical point of view is when you are studying functions by using a table of values. The verbal point of view is when you are studying functions by using (descriptive) words. The visual point of view is when you are studying functions by using leveled curves and graphs. D (the set) would be the function"s domain while the actual set of values that the function is taking on would be the range, which can written as the following: {f (x, y) | (x, y) d}
