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 …

May 28, 2013 · 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 …

Jul 23, 2014 · 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 …

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., sin2x+cos2x= 1 sin 2 x + cos 2 x = 1 is true for all …

Oct 2, 2011 · I need to graph a rectangle on the Cartesian coordinate system. Is there an equation for a rectangle? I can't find it anywhere.

May 30, 2019 · Given two discrete points on a log-log plot and a defined minimum value on both axes, how would you determine the equation of the line that runs through both points?

Oct 9, 2024 · I feel the Fokker-Planck equation is fairly well explained here and there in the applied literature, while the backward equation mostly shows up in mathematics books that are both very …

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 ...

Apr 20, 2017 · Get the equation of a circle through the points $(1,1), (2,4), (5,3) $. I can solve this by simply drawing it, but is there a way of solving it (easily) without having to draw?
