Kosunen, "Periodic orbits 1-5 of quadratic polynomials on a new coordinate plane
The center point is located in the 1st quadrant and does not represent the Cartesian coordinate plane
Furthermore, the power of the coordinate approach is that from the list of coordinates alone, the graph can be transferred to any setting--another student, a computer program, or even the wall--where a coordinate plane
2 and 3 demonstrate the trajectories of the points on the surface of the oscillating scattererpendulum hemisphere in 3D space and their projections on the XOZ and XOY coordinate planes
for the time interval of 0<t<5 s.
Some lessons teach math concepts by using the robot to visualize coordinate planes
, degrees of movement and limitations.
In response to low achievement in mathematics at a middle school, an ethnomathematic approach was used to teach coordinate planes
. Whether there were achievement differences between students taught by the culturally sensitive approach and those taught by a traditional method was studied.
Maps of misfit functions are presented in three coordinate planes
containing the minimum.
The author states, "The central object in all the activities in this publication is to help students build mental images of fractional parts and operations on fractions." To reach this objective, Wiebe developed a comprehensive set of activities based on seven different concrete fraction models: pattern blocks, fraction rulers, fraction circles, unit bars, unit squares, egg cartons, and fractions on coordinate planes
. As students explore the activities, they develop their understanding of equivalent and nonequivalent fractions; addition, subtraction, multiplication, and division of fractions; and proportional reasoning.
After excitation frequency for stable and steady part alignment was experimentally set to all pegs (Table 1), motion trajectory of the tip was taken in all three coordinate planes
. Excitation frequency mainly depends from the peg's natural frequency, design of the gripper and force F2.
