用弧度度量的角与三角函数的基本知识; 实轴上的三角函数(不只是介于00和900;三角函数的图像;三角恒等式。 2.1 基本知识 首先要回忆的是弧度的概念。旋转一周,我们说成2 π\piπ弧度而不是3600。半径为1个单位的圆的周长是2 π\piπ个单位,这个圆的一个扇形的弧长就是这个扇形的圆心角的弧度。 用弧度 ...
Compare the accuracy ofsinpi(X)vs.sin(X*pi). Create a vector of values. X = [0 1/2 1 3/2 2]; Calculate the sine ofX*piusing the normalsinfunction. Y = sin(X*pi) Y =1×50 1.0000 0.0000 -1.0000 -0.0000 The results contain small numerical errors due to the fact thatpiis a...
