- What is the difference between equation and formula?
An equation is meant to be solved, that is, there are some unknowns A formula is meant to be evaluated, that is, you replace all variables in it with values and get the value of the formula Your example is a formula for mpg But it can become an equation if mpg and one of the other value is given and the remaining value is sought
- 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
- 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
- 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
- General equation of a plane through $3$ points. [closed]
Note that there are 4 unknowns, so there is no single solution for a,b, and c since you can just multiply the equation by some constant and it stays the same, so you just solve for ratio of a to b to c Also if there is no single solution, then there is a solution set (multiple planes can satisfy the conditions)

- intuition - How Bernoulli differential equation arise naturally . . .
A Bernoulli differential equation is a non-linear differential equation of the form $$ \\frac{dy}{dx} + P(x)y = Q(x)y^n $$ I understand this is special; Because its exact solution is known though
