I'm having trouble with this question...
To find the minimal point, is there an easier way other than plugging in all possible values?
Compute the polar coordinates and the xy-coordinates for the point where y is maximal
on the graph of the polar coordinate equation .
Sorry, yes, I meant maximum.
Could you explain why you set dy/dt = 0.. is that because when dy/dt = 0, then the slope is horizontal, and we must be at a maximum point? I just want to make sure I understand.
If I were asked to find the minimum, would I first multiply by cos(t) and then try to calculate dx/dt? Would I also set that to 0 to find the minimal point?
Thanks for your help!
