I'll give it a go... What is the maximum number of times (##N## ) a circle* can intersect the graph of ##y=\sin x##? a)##N \le 2## b)... -
Vvcsharp2003 replied to the thread Intersection of a circle and a sine curve.It seems that none of the options given in the challenge problem under post#13 is true. I counted the number of intersections in post#10...

You didn't try to move the circle. The problem statement doesn't forbid this.

Good one. A simple version would be ##x^2+(y-r)^2 = r^2##, where ##r## can be a parameter. You can easily get as many intersections as...

Over the range of allowable a, b, r, parameters there is no maximum. It might be possible to determine (or bound) the number of...

Right. Is the problem statement complete and accurate?

Vvcsharp2003 replied to the thread Intersection of a circle and a sine curve.If it's a straight line there would be many peaks of the sin wave that it would touch. If we take it further down so it is on the x-axis...
