Ok, I get it now. I seem to vaguely remember an animation that showed this.

Its the first question. I do not understand how you can get a smaller circle when you shift the square. Maybe I'm doing it wrong but I thought that when you shift the square, the end points of the square move along the circle. The diagonals of the square will be equal to the diameter of the...

How do you determine if a point lies on the sides of a square inscribed on a circle ? I'm given only the radius of the circle and the circle is centered at the origin. My idea was to find the equation for each side and then to test the given point. However, I just realized that you can...

I have the following equation F[i] = (F[i-1] * a) % b, F[0] = 1; Values of a and b are given. My question is whether it is possible to mathematically determine the value of i if you are given F[i].

Suppose you are given a number 35, how can you say if the number can be written as the sum of unique powers of a number ? For example, 11 cannot be written as a sum of powers of number 3. But 13 can be written as follows : 30 + 31 + 32 = 15 I hope my question is clear.

I have this problem where I'm having trouble solving so any help would be appreciated. Here's the problem: You have a balancing scale and a set of unique weights. Each weight that you have is a power of 3 ie you have weights 1,3,9,27 etc. You are given a weight w. The problem is to tell...
