Solution to Example 1. We first solve the linear equation for y as follows: y = - x - 1/2. We now substitute y in the equation of the circle by - x - 1/2 as follows. (x - 2) 2 + (- x - 1/2 + 3) 2 = 4. We now expand the above equation and group like terms. 2 x 2 - 9 x + 25/4 = 0. Solve the above quadratic equation for x to obtain two solutions.. The general equation is x 2 + y 2 = r 2, so the equation when r = 4 is: x 2 + y 2 = 4 2. x 2 + y 2 = 16. Example: What is the equation of the circle centered at the origin with diameter 10? Solution: We are told that d = 10. Since the radius is one-half of the diameter, r = 5. The general equation is x 2 + y 2 = r 2, so the equation when r = 5 is:. The circumference can be found by the formula C = πd when we know the diameter and C = 2πr when we know the radius, as we do here. Plugging our radius of 3 into the formula, we get C = 6π meters or approximately 18.8495559 m. Now we multiply that by (or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters.

Method 2. To determine the position of a line with respect to a circle, all we need to do is find its distance from the center of the circle, and compare it with its radius. Then, if the distance is less than the radius, the line must intersect the circle at two distinct points. if the distance is equal to the radius, then the line will touch.

Explanation: To determine x -intercepts of any function y = f (x), we put y = 0. (and we put x = 0 to find y -intercepts). Hence x -intercepts are given by f (x) = 0. and here sin( πx 2) +1 = 0. or sin( πx 2) = −1 = sin( 3π 2) Therefore πx 2 = 2nπ +( 3π 2), where n is an integer. This happens as in the domain 0 < x < 2π, only for sin ...
