About this deal
Default differentiation variables for d_, D_ and dAlembertian are: X = x , y , z , t Color/Appearance: Unlike most other hardwoods, the sapwood of hard maple lumber is most commonly used rather than its heartwood. Sapwood color ranges from nearly white, to an off-white cream color, sometimes with a reddish or golden hue. The heartwood tends to be a darker reddish brown. Birdseye maple is a figure found most commonly in hard maple, though it’s also found less frequently in other species. Hard maple can also be seen with curly or quilted grain patterns. Our solid maple wood flooring is manufactured from sustainably sourced prime grade Canadian maple. The wood has a light, subtle grain pattern and an even colour tone. The boards will mellow over time and develop and warm golden hue. Traditionally maple was used as a sports floor due to its high strength, it is also a popular choice of wood flooring for many homes and contrasts beautifully with dark furnishings.

Retrieved September 9, 2021.The distinction between covariant and contravariant indices is relevant in non-Euclidean spacetimes (you can set the spacetime to be Euclidean by entering Setup metric = Euclidean ). For example, in a flat Minkowski spacetime, when summing over the repeated indices of tensorial expressions (see SumOverRepeatedIndices ) >

While all the information is present and the typesetting has textbook quality, this display has redundancies. With paper and pencil we would omit the functionality x , y , z , t when writing such formulas, and possibly represent the derivatives indexed . For example, the expression above would be written as Define R α , β , μ , ν , symmetric = α , β , μ , ν , antisymmetric = α , β , μ , νIn Maple tensor indices are letters , lowercase or uppercase, Latin or Greek , just like when computing with paper and pencil. The indices are entered using indexation, as in A mu , and are displayed as subscripts as in A μ . To change or set the kind of letter ( greek, lowercaselatin, etc.) used to represent a kind of index ( spacetime, space, etc.) see Setup .
