The leftmost panel of the Scratch window is imagined to be Cartesian plane
. The centre of the panel has coordinates (0, 0), with positive x-coordinate values to the right, and positive y-coordinate values upwards, and correspondingly negative coordinate values to the left and below the central origin.
Thus, in the dimensions of the Cartesian plane
, the variables that explained the variability on the x-axis (PC1) were fat (r=0.84, P <0.001), PROT (r =0.75, P <0.001) and TDE (r =0.99, P <0.001).Variables that explained the variability on the y-axis (PC2) included LACT (r=-0.86, P <0.001), the SCC (r =0.50, P <0.001) and the TBC (r =0.62; P <0.001).
They hit upon the idea to represent imaginary numbers as points on a plane similar to the Cartesian plane
like the one devise by Rene Descartes in the 17th century.
The first is the value of X, Y, and Z of the Cartesian plane
where the end effector is located, the second is the destination point, and the third belongs to the via point.
rTAG projects a Cartesian plane
onto a white floor mat, upon which a LEGOA robot named Quinn navigates.
We will assume conductors perpendicular to XY Cartesian plane
and define i and j as the corresponding unit vectors.
From answering seatwork to doing scientific experiments with indigenous materials, from solving mathematical equations to drawing a butterfly on a Cartesian plane
, from theories to job skills, these were among the innovations in the new curriculum observed by teachers interviewed by the Inquirer.
A proof, which is based on algebraic manipulation of coordinates in Cartesian plane
, is less explanatory (but connects geometry to algebra).
As in the earlier example, the area involved is small enough that a rectangular Cartesian plane
can be safely used, and the issue of the earth's curvature, and thus of projection, can be ignored.
Progressing along its lone axis, the book is a sequence of 294 different dissections of the Cartesian plane
. It's a difficult kind of dimensional collapse, arranging the planar into the linear, though imperfect at moments, Nicolai is at home working within self-imposed constraints.
The graphs-alive activity that asks students to stand when the coordinates assigned to their desks exhibit some particular characteristic hints at using a Cartesian plane
to represent the relationship between two variables.
