Hi,

I am using Matlab to plot the sin graph. But when I put sin(2*50*pi*t) it shows something else than the sinusoidal curve. Can you please help me to find out why it is happening? Thanks in advance.

Code:

t = 0:0.1:20;

x = sin(2*50*pi*t);

y = sin(2*1*pi*t);

subplot(2,1,1)

plot(t,x)

subplot(2,1,2)

plot(t,y)

t1 = 0:0.001:1;

x = sin(2*50*pi*t1);

t2 = 0:0.1:1;

y = sin(2*1*pi*t2);

subplot(2,1,1)

plot(t1,x)

subplot(2,1,2)

plot(t2,y)
