In trig how is the value of r interpreted geometrically in the definitions of the sine cosine secant and cosecant?
In trigonometry, the value of R is the radius of the circle, and is usually normalized to a value of 1. If the circle is at the X-Y origin, and theta is the angle between the radius line R, and X and Y are the X and Y coordinates of the point on the circle at the radius line, then... sine(theta) = Y / R cosine(theta) = X / R secant(theta) = 1 / cosine(theta) = R / X cosecant(theta) = 1 / sine(theta) = R / Y
If the area of a circle and its circumference have the same numerical value what is the length of the radius?
Area = pi*r2 = 2*pi*r = circumference then r2 = 2r so that r = 2
Formula to find circumference of quadrant?
Circumference of a circle = 2 * pi * r pi = 3.1415926535897932384626433832795 r= radius of circle Hence Circumference of a Quadrant = 2 * pi * r / 4 = pi * r / 2 = 0.5 * pi * r For more accurate value of pi, please refer: http://en.wikipedia.org/wiki/Pi
There is a piece of string wrapped tightly around the earth How much longer would the string need to be if there was a gap of 1 meter between the string and the earth?
This is a minor geometrical calculation in which the radius of the object the string circles is irrelevant. If the radius of the Earth is 'r', then the length of the tight string = 2π(r) The increase of 1 metre is an increase of the radius to r+1, so the new length is 2π(r+1) If we give π a value of 3.1416, then the old length is the string was 6.2832(r) and the new length is 6.2832(r+1) or 6.2632(r) + 6.2632 So, as we don't put a value on (r), this actually means that if the string is around a pea or the earth the extra length needed to loosen it by 1 metre all around is 6.2632 metres and is the same in either case.
