I have to print tangent function in a range from 0 to 2*pi and I dont know how to do that as tangent goes to infinity at some points. Here's my code, could anyone help please?
t = 0:0.01:2*pi;
y = tan(t);
plot(t,y)
xlabel('x')
ylabel('y=tan')
grid on

Ran in:
t = 0:0.01:2*pi;
y = tan(t);
plot(t,y)
xlabel('x')
ylabel('y=tan')
axis([0 2*pi -5 5]) % set the x-axis to go from 0 to 2*pi, and the y-axis to go from -5 to 5
grid on
