how do i plot y=6sin(t+0.5) and y=5 between 0 and 20 in steps of 0.001

how do i plot y=6sin(t+0.5) and y=5 between 0 and 20 in steps of 0.001

Hint - colon, : and plot

If you want help with a particular problem, show your code and ask a specific question.

Hint:

colon, :

plot

yline

[Zack]

x= 0 : 0.001 : 20;
y1= 6*sin(t+0.5);
y2= 5;
plot(t,y1,t,y2)
grid
xlabel('x units')
ylabel('y')
getting a error for y1. any help is much appricated 

[Torsten]

You don't define t in your code. Shouldn't it be x ?

And if you do it this way:

y2 = 5*ones(size(x))

instead of

y2 = 5

Hi Zack

The following code will display the plot as required

x= 0 : 0.001 : 20;
y= 6*sin(x+0.5);
plot(x, y, 'green')
hold on
yline(5, 'red')
grid
xlabel('x units')
ylabel('y units')
hold off

Hope it helps !
