Now I see that I wasn’t clear with “with the above” (sorry about that!); by that I meant all the way up to the x,y solution for nonnegative y (this is why I cut into the post midsentence, so that t’s introduction would be below rather than above); or, in other words, up to the following: (09132021 07:42 PM)Albert Chan Wrote: ⋮ (It seems to me that the x>0,y=0 portion is missing.)

I enjoyed imagining a line going through the origin with the slope varying, and thinking how that related to the problem (and your given solution set for t).
