Vector projection of a on b (a 1), and vector rejection of a from b (a 2). In mathematics, the scalar projection of a vector on (or onto) a vector , also known as the scalar resolute of in the direction of , is given by:
The scalar projection a on b is a scalar which has a negative sign if 90 degrees < θ ≤ 180 degrees. It coincides with the length ‖c‖ of the vector projection if the angle is smaller than 90°. More exactly: a 1 = ‖a 1 ‖ if 0° ≤ θ ≤ 90°, a 1 = −‖a 1 ‖ if 90° < θ ≤ 180°.
The "Type" column refers to the type of circuit: "street" is a circuit held on closed city streets, "road" refers to a mixture of public roads and a permanent track, and "race" is a permanent facility. The "Last length used" shows the track length for the configuration that was used last time the Formula One race was held on a given track.
There are 38 Grade One circuits with 45 layouts. Circuits holding Grade One certification may host events involving "Automobiles of Groups D (FIA International Formula) and E (Free Formula) with a weight/power ratio of less than 1 kg/hp." [1] As such, a Grade One certification is required to host events involving Formula One cars.
Vertical layout is the track layout on the vertical plane. This can be thought of as the elevation view which is the side view of the track to show track elevation. In track geometry, the vertical layout involves concepts such as crosslevel, cant and gradient.
In mathematics, the dot product or scalar product [note 1] is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors), and returns a single number. In Euclidean geometry , the dot product of the Cartesian coordinates of two vectors is widely used.
The track is characterised by its 1.8 km (1.1 mi) long Mistral straight and elongated track design. The track is also unusual in that it is built on a plateau : it is very flat. In 1986 the track was modified to shorten the circuit, by adding shortcut through to the middle of the Mistral Straight.
It is a signed scalar quantity, formulated as the scalar projection of the relative velocity vector onto the LOS direction. Equivalently, radial speed equals the norm of the radial velocity, modulo the sign. [a]
