can someone help me write a program for MATLAB for cos(theta)
SO FAR I HAVE:
clc
clear
theta=0:pi:4*pi;
plot(theta,cos(theta))
xlabel('theta')
ylabel('cos(theta)')
grid off
for some reason it's display the graph not 'curve' and it's not display the x values a 0,pi,2pi,3pi,4pi...
someone help please :/
