【解析】曲线c的参数方程为:=sin[ y= cos 20 且cos20=1-2sin20,sin∈[-1,1]消去参数,化为普通方程是:y=1-2x2,z∈[-1,1]故答案为:y=1-2x2,x∈[-1,1]【参数方程与普通方程的互化】1.参数方程化为普通方程基本思路是消去参数,常用的消参方法有:①代入消元法;②加减消元法;③恒等式(三角的...
For real values ofX,cos(X)returns real values in the interval [-1, 1]. For complex values ofX,cos(X)returns complex values. Examples collapse all Plot Cosine Function Plot the cosine function over the domain−π≤x≤π. x = -pi:0.01:pi; plot(x,cos(x)) gridon ...
removal functionComputer controlled optical surfacing (CCOS) technique is widely used in machining process of large and medium aspheric surfaces, because of its high accuracy, simple process conditions, low cost and other merits. The characteristic of the removal function of a polishing tool is a ...
