The straight line through the origin and a point on the circle has the slope ##\dfrac{\sin \omega}{\cos \omega}.## This means that the... -
Vvcsharp2003 replied to the thread Family of lines that are at a distance of 5 from the origin.I get that since a tangent to a circle will always be perpendicular to its radius. But, the question still remains how the one-liner...

Vvcsharp2003 posted the thread Family of lines that are at a distance of 5 from the origin in Precalculus Mathematics Homework Help.I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the...

They are writing a textbook. It is their job to worry about clarity. A nd where were the editors.....? I am very critical. More so...

I would say ""out of all possible circles, what is the maximum number of times any circle can intersect the sine function." IMO, that...

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)...

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...
