６．The figures in the changed coordinates plane
we attempt to see how a figure will change when changing the whole coordinate plane, and when changing the figure usng a figure,too. From these things, if there is a new coordinate system, the figure can be written there from the beginning, too.
Let's attempt to think of changing a figure using function w=z2. The following new coordinates plane was used for this change. First draw a figure at the house like the one on the right.
The mouse pen is used to plot the point of the new coordinate system, which correspond to the coordinates of the original points. It is necessary to carefully trace the points with the mouse pen. ( For the function w=z2, be careful because the starting point is the same before and after. )
It is in the same way, there is example given about w=ez, too. By changing a coordinate plane base in this way , the figure can be easily pictured.
