Webbr = a sin ( 2 θ) = 2 a cos θ sin θ. Multiplying each side by r 2 we get r 3 = 2 a ( r cos θ) ( r sin θ), which in cartesian coordinates is ( x 2 + y 2) 3 2 = 2 a x y. Since the left-hand side is positive, you should only draw points if 2 a x y ≥ 0, so only in first and third quadrant if a > 0. If we square both sides than we get Webb2 jan. 2024 · 以下是用 MATLAB 绘制正多边形逼近圆周率值的代码： n = 100; % 正多边形的边数 r = 1; % 圆的半径 theta = linspace(, 2*pi, n+1); % 计算正多边形的顶点坐标 x = r*cos(theta); y = r*sin(theta); pi_approx = zeros(1, n); % 存储逼近的圆周率值 for i = 3:n pi_approx(i) = i*sin(pi/i); % 计算逼近的圆周率值 end figure; plot(x, y, 'k'); % 绘制圆 ...
