comment Hanging a picture on the wall using two nails in such a way that removing any nail makes the picture fall down
@Georgy - This illustrates that the problem needs to be specified a little more formally.

comment Does 17% have to be equal to 0.17?
They are only different when you are informally using "17%" to be slang for "17% of x". For example, "I will add 10% to your salary" is really slang for "I will set your new salary to be your current salary plus 10% of your current salary".

comment Do we know if there exist true mathematical statements that can not be proven?
If a logical argument allows you to end with "Hence it is true", how is that not a proof?

comment Dot product with a difference maximum angle
In that case, use x = angle_in_degrees/(90 * range). For example, 45/(90*0.5) = 1.

comment Dot product with a difference maximum angle
If you are converting from degrees to your new unitless [0,1] range, then it is x = angle_in_degrees/maximal_angle.
