I have two similar coins, one is kept static and other is revolving the static one without any slip. Can you explain theoretically how many revolutions will be made in the dynamic coin?
Thanks!
For a given linear equation and some (x,y) points, need to know if that lies in the line or above or below the line?
Thanks!
I have 2 circles (let us say A and B) of equal diameter, and they overlap each other by passing through the center point of each other (ie the path of one circle passes through the center point of the other circle). Let us name the common region as C, now what is the perimeter of the C? I am not sure if C is a circle.
Thanks!
Excellent!
Thanks,

Yes Luca, that must be right, even the perpendicular line will start from the center of the chord inorder to have the maximum distance.

How to find the area of the smallest piece of the remaining circle, that is cut by a chord?
The maximum distance between the line segment (that makes right angle) from the line to end of the circle edges is considered height which is known together with the radius of the circle.

Hi Ricky & co,
Thanks for the quick answers, the link also explains very cool about Permutation with repetitions.
just to make thing clear, 4 out of 8, where 8 is the available colors, there are enough balls in the sack.
Best regards,
Stanley
Hi,
How can this be computed? There are n different color balls and I pick m balls. What is the total possible combinations that can be expected? Note the balls may or may not repeat x times and the order is important.
Let me place this in example terms, In a sack of 8 different color balls, I am to pick four. What is the total possible combinations that can be expected?
For example let us say I picked 4 out of 8 Red Green Green Black and that is different from Black Green Green Red.
Thanks,
Stanley
