matlab求助：x=[0,4*pi]; a=sin(x); plot(x,a); 用这个画sin函数 错在哪里?

matlab求助：x=[0,4*pi]; a=sin(x); plot(x,a); 用这个画sin函数 错在哪里? matlab中语句 >>x=0:10/pi:2*pi; >>sinx=sin(x); >>figure,plot(x,s Matlab的作图命令,x = 0:pi/100:2*pi; y = sin(x); plot(x,y) 我的matlab程序哪里错了? t=0:0.01:2*pi x=cos(t)^3 y=sin(t)^3 plot(x,y syms a x y x=sin(a) y=cosh(x) a=linspace(0,2*pi) plot(a,y) 错 matlab问题,>> t=0:0.2:3*pi;x=exp(-t).*sin(t);plot(t,x) >> t=0: x=-pi:0.1:pi; fh={@cos,@sin}; plot(fh{2}(x)) 刚学习matlab,谁帮我解释 a*sin(pi/4 - x) - b*cos(pi/4 - x) = a*sin(pi/4 + x) - b*cos( 如何用matlab画y=267*sin(x)*sin(x)*cos(x);在（0 2pi）区间 matlab中y=(0.5+3.*sin(x*pi/180)./(1+x^2)).*cos(x*pi/180);哪里错了 matlab基础 x=0:0.1:2*pi;y1=sin(x);y2=cos(x);z=[y1,y2];plot(x,z x=0:pi/100:2*pi y=2*sin(x+2)+4*x+3 q=plot(x,y)的运行结果代表什么
