- What is the difference between equation and formula?
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
- What is the equation for a 3D line? - Mathematics Stack Exchange
I love your answer for a line equation in the form of z = f (x, y) Unfortunately calculating square roots can be impractical from the calculational standpoint and hence I really doubt any plotting software will be able to graph it correctly
- simple geometry question- equation of cylinder
The equation of an object is a way of telling whether a point is part of an object -- if you substitute the coordinates of the point into the equation and the equation is true, then the point is on the object; if the equation is not true for that point, then the point is not on the object
- Transformations of the circle equation - Mathematics Stack Exchange
I know to translate the circle equation we just need to change the values in the brackets of the general circle equation $ (x-x_1)^2+ (y-y_1)^2=r^2$ , and in order to dilate a circle we need to double the value of the radius i e times by $2^2$, however when it came to stretching and squeezing, I am confused if there is even a predictable method
- Equation of a rectangle - Mathematics Stack Exchange
I need to graph a rectangle on the Cartesian coordinate system Is there an equation for a rectangle? I can't find it anywhere
- What is the difference between an identity, an equation and a . . .
Equation means equality They are both related to the word equal If such an equality is true for all values of the variable, it is called an identity, e g , $\sin^2x+\cos^2x=1$ is true for all x If however the equation in question only holds for some values, which one is supposed to determine, then it's called conditional, and its variable is termed an unknown
- linear algebra - Equation of a plane passing through 3 points . . .
First consider the equation we use to describe a plane: $$ ax + by + cz + d = 0 $$ Why is it this way? let's first imagine a way to describe the point set of a plane: a plane must have a normal vector, and an “offset” to determine its exact position What about the points on it? All the points are the same distance away from origin point
