Cubic CentimetreSymbol: cm3. A unit of volume. The three-dimensional space equivalent to a cube with edge length 1cm. |
Cubic CurveA curve described by an algebraic equation containing at least one cubic term, i.e. a term raised to the power of three, and no terms with higher powers than three. |
Cubic MetreSymbol: m3. A unit of volume; a three-dimensional space equivalent to a cube of edge length 1m. |
CuboidA three-dimensional figure with six rectangular faces. Different to a cube in that the lengths of the sides are not necessarily the same; a 3D rectangle. |
CylinderA three-dimensional object whose uniform cross-section is a circle. A right cylinder can be defined as having circular bases with a curved surface joining them, this surface formed by line segments joining corresponding points on the circles. The centre of one base lies over the centre of the second. |
DataInformation of a quantitative nature consisting of counts or measurements. Initially data are nearly always counts or things like percentages derived from counts. When they refer to measurements that are separate and can be counted, the data are discrete. When they refer to quantities such as length or capacity that are measured, the data are continuous. Singular: datum. |
DatabaseA means of storing sets of data, for example in an Excel spreadsheet. |
DecimalRelating to the base ten. Most commonly used synonymously with decimal fraction where the number of tenths, hundredth, thousandths etc. are represented as digits following a decimal point. The decimal point is placed at the right of the units column. Each column after the decimal point is a decimal place. Example: The decimal fraction 0.275 is said to have three decimal places. The system of recording with a decimal point is decimal notation. Where a number is rounded to a required number of decimal places, to 2 decimal places for example, this may be recorded as 2 d.p. |
Decimal FractionTenths, hundredths, thousandths etc. represented by digits following a decimal point. Example 0.125 is equivalent to 1/10 + 2/100 + 5/1000 or 125/1000 or 1/8 The decimal fraction representing 1/8 is a terminating decimal fraction since it has a finite number of decimal places. Other fractions such as 1/3 produce recurring decimal fractions. These have a digit or group of digits that is repeated indefinitely. . |
DegreeIn the measurement of angles, a unit of turn, usually clockwise. One whole turn is equal to 360 degrees, written 360o. |
