matlab解方程画图2*tan(0.5*sqrt(8*x^2-y^2))/(sqrt(8*x^2-y^2))-tan(sqrt(x^2-y^2))/sqrt(x^2-y^2)=0,其中x=4*pi*sqrt(8.854*4*pi*10^(-19))/f,求画出f-y的曲线,其中0写错了，其中x=2*pi*sqrt(8.854*4*pi*10^(-19))*f

>> ezplot('2*tan(0.5*sqrt(8*(4*pi*sqrt(8.854*4*pi*10^(-19))/f)^2-y^2))/(sqrt(8*(4*pi*sqrt(8.854*4*pi*10^(-19))/f)^2-y^2))-tan(sqrt((4*pi*sqrt(8.854*4*pi*10^(-19))/f)^2-y^2))/sqrt((4*pi*sqrt(8.854*4*pi*10^(-19))/f)^2-y^2)=0',[0,40])
不过图貌似不太好啊!0
