Hello, hope you're doing well.

I want to plot the attache sine graph with 50 cycles and 33 sec. I have tried several codes but didnt work.

Could someone help me with that?

Thanks in advance.

By 50 cycles, I understand that you mean that over 33 seconds the signal should have 50 periods.

>> t = 0:(1/50):33;

>> x = 2*sin(2*pi*50/33*t);

>> figure, plot(t, x)

thanks I appreciate that.
