- 在理工科中，Formula, Equation 和 Function 这三个词有什么异同？ - 知乎
equation：等式，方程式 英英释义： An assertion that two expressions are equal, expressed by writing the two expressions separated by an equal sign; from which one is to determine a particular quantity
- 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
- simple geometry question- equation of cylinder
All points on it have x=0 and y=0 Clearly it is a line with any z-allowed You could write the equation of the axis as x2 +y2 = 0 x 2 + y 2 = 0, because in the reals the only solution to this equation is x = 0 x = 0 and y = 0 y = 0 This shows you that the z-axis is like an infinitely thin cylinder (with a point cross section 0 radius)
- 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
- geometry - Get the equation of a circle when given 3 points . . .
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?
- linear algebra - Equation of a plane passing through 3 points . . .
In fact, it’s possible to do better and write down an equation of the plane directly Every other point (x, y, z) (x, y, z) on the plane also generates a linear equation in the coefficients of the plane equation
- logarithms - Finding the Equation of a Straight Line on a Log-Log Plot . . .
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?
- General formula for solving quartic (degree $4$) equations
Could you change the title to "Is there a general formula for solving 4th degree polynomial equations" or "Is there a general formula for solving quartic equations?"
