How to plot the graph of cos function for specific value of Pi in Matlab? -


for specific function,

x(n) = cos(ωn+θ) , ω = π/6 , , θ = π/3

i unable plot graph.

for general cosine function, can plot using:

x = -pi:0.01:pi; plot(x,cos(x)) 

but how plot graph specific pi values of omega , theta?

other defining constants first...

w = pi/6; th = pi/3; = 1; 

then plotting them?

n = -pi:0.01:pi; plot(n, a*cos(w*n + th) );
