An equation is any expression with an equals sign, so your example is by definition an equation. Equations appear frequently in mathematics because mathematicians love to use equal signs. A formula is a set of instructions for creating a desired result. Non-mathematical examples include such things as chemical formulas (two H and one O make H2O), or the formula for Coca-Cola (which is just a ...
It seems to me an equation, in an abstract sense, must always involve some varying quantities where the varying quantities belong in some space (set, algebraic structure, what have you). In order to
As I am progressing differential equations practice, I found myself at somewhat of a roadblock. The roadblock is essentially that let's say we have the following equation:$$\int x^2\,dx=\int y\,dy....
What are the equations to calculate a linear trendline over a set of points? EDIT: "In excel it is done automatically but how to manually calculate a linear trendline over a set of points" was orig...
This jingle has helped generations of algebra students recall the quadratic formula that solves every equation of the form $latex ax^2+bx+c=0$. The formula is as ...
