Answer:
Is the DIAMETER of a circle proportional to its circumference??
1. One of the unique qualities of a circle is that its diameter and circumference have a proportional relationship.
2. This means that no matter what size the circle is, the proportional relationship, or ratio, between its circumference and diameter is always the same.
Is the RADIUS of a circle proportional to its area??
1. Yes, the circumference of a circle is proportional to its radius.
2. Double the radius and you double the circumference.
Cos(2x) = cos^2(x) - sin^2(x) - cos(x)
but sin^2(x) = 1 - cos^2(x)
cos(2x) - cos(x) = cos^2(x) - (1 - cos^2(x) ) - cos(x)
cos(2x) - cos(x) = cos^2(x) - 1 + cos^2(x) - cos(x)
cos(2x) - cos(x) = 2cos^2(x) - 1 - cos(x)
cos(2x) - cos(x) = (2cos(x) + 1)(cos(x) - 1)
I think this is what you have asked for.
