- 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
- Difference between ≈, ≃, and ≅ - Mathematics Stack Exchange

- Polar equation of a circle - Mathematics Stack Exchange
A very long time ago in algebra trig class we did polar equation of a circle where r = 2acosθ + 2bsinθ Now I forgot how to derive this So I tried using the standard form of a circle (x − a)2 + (y − b)2 = a2 + b2
- 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
- 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)
