Cricle ― 2012/12/24 00:00:00
One of my students, who is a senior class student in my university, surprised me the other day. I just asked him in our conversation:
"Tell me what the equation x2+y2=r2 denotes?"
Just to give you an idea, our major is mechanical engineering, so elementary mathematics is necessary to write the graduation thesis. However, he answered:
"I forgot it."
So, I told him:
"It denotes the circle. Tell me the center and radius of this circle, then."
After a short silence, he answerd:
"The center is r. The radius is x and y."
I had nothing to say to him any more. I wish him luck :).
