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. …

May 28, 2013 · If we want an equation f(x, y) f (x, y) for the line, the domain of f f can only be the shadow of the line on the xy x y plane. But any nice function f f will have as a domain either all …

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 …

Reflecting a function along the line y = x is the same as computing the inverse of the function. So use a method for computing the inverse of a function to find the reflection about the line y = x.

Jul 28, 2010 · For cubic equations of the form , there is a set of three equations, one for each root. Is there a general formula for solving equations of the following form [Quartic Equations]?

Oct 14, 2017 · Suppose we have the plane with equation 3x − 7z = 12. How to find its normal vector? The plane with equation Ax + By + Cz + D = 0 has the normal vector n = (A, B, C). …

I want to get her to notice me by graphing a heart on my TI calculator but I don't know if there's a single mathematical equation that can draw this when it graphs the line.

The second angle is used in polar coordinates in the standard ellipse and is measured from center of the circles. We call it θpolar as usual. Green radial line. For an ellipse axes (a, b) along (x, …

Dec 20, 2018 · The line l1 l 1 has the equation r = (6i + 2j − 2k) + λ(4i + 5j − k) r = (6 i + 2 j − 2 k) + λ (4 i + 5 j − k) and the plane π1 π 1 has the equation 2x − y + 4z = 4 2 x − y + 4 z = 4. The …

EDIT1 If the discriminant of this quadratic equation that is the real guide is (> 0, 0, <0) then the intersections are respectively (2, 2 coinciding points at tangent,2) in number which are the …
