how to solve and plot complex equation
显示 更早的评论
Trying to plot the bottom equation where x is 0-180 degrees. I believe the sin within the [] of the sin is where I'm messing up.
a=(b*Pi*sin(x))/c
b and c are constants
x=0-180 degrees
y=(sin^2(a))/a^2

b = 3; c = 4;
x=0:180;
a=b*pi*sin(deg2rad(x))/c;
y=(sin(a).^2)./a.^2;
plot(x,y)

A couple of things: pi needs to be lowercase and you need to use .*, ./, and .^ when doing element-wise operations on vectors or matrices. I hope this helps!
a = 2;
b = 3;
c = 4;
x=0:180;
a=(b*pi*sin(x)) ./c;
y=(sin(a).^2) ./ a.^2;
plot(x,y)
