Finding central angle
WebSep 17, 2024 · Note that to name a minor arc, you use its two endpoints; to name a major arc, you use its two endpoints plus any point along the arc. Central angle: A central angle is an angle whose vertex is at the center of a circle. The two sides of a central angle are radii that hit the circle at the opposite ends of an arc—or as mathematicians say, the … WebApr 12, 2024 · From the documentation page for the angle function: "theta = angle (z) returns the phase angle in the interval [-π,π] for each element of a complex array z. The angles in theta are such that z = abs (z).*exp (i*theta)." If you want the angles to be in the interval [0, π] instead add the negative angle to 2*pi. Theme.
