change of variables introduction part 1

[MrJaeger2000]

He chooses x=(v-u)/2 and the y= from the motivations behind the transformation. It is a personal decision. By transforming into this new coordinate system, perhaps the problem can be solved easier or visually more appealing for an intuitive understanding. kind regards, Ian Gregory, Sydney.

How did you get the x=(v-u)/2 and the y= equations?

[nakeder]

One mistake. In the change of variables from polar to x and y, the angle theta varies from zero to pi/2 and not pi/4.

[innpinn]

@nakeder no he's specified in the x,y that theta only goes to pi/4. in general theta does vary between 0 and pi/2 but here he's given an example where only the region where theta is less than pi/4 is included.
