What is a point circle, a real circle and an imaginary circle?

Web25 jan. 2009 · Computationally, there are quicker ways. Define: dx = abs (x-center_x) dy = abs (y-center_y) R = radius. If a point is more likely to be outside this circle then … WebThe angle of elevation is 30° and the length of the cable is 34.6 meter Step-by-step explanation: using pythagorean theorem a^2 + b^2 =c^2 30^2 + 10sqrt (3)^2 = c^2 900 +300 = c^2 1200 =c^2 c = sqrt (1200) c = 20sqrt (3) or 34.6 meter solving the angle: tan∅ = b/a tan∅ = 10sqrt (3) / 30 arctan = 10sqrt (3) /30 arctan = 30 ° WebBut if you want to find angular velocity, simply divide the angle traveled in radians by the time it took to rotate at that angle. The general equation is as follows: ω = (θ/t) where omega (ω) is in radians per seconds, theta (θ) is in radians, and t is in seconds. Comment … staying clear by cori smith free pdf
