Sketching Sine Wave in Matlab

MATLABsinewave

I am working with matlab in college and I need to generate sine wave whcih represents signal going through a wire.

But its not clear to me what t equals to and how can I multiply \$y\$ by \$t\$

this is the formula

$$y(t) = 1.2\sin(35.000\pi t+2.15\text{ rads})$$

This is my Matlab code

time = 1:1.0:10;
radstodegrees = 2.15*180/pi
y = 1.2*sin(35.000*pi*time*radstodegrees);
y = y*time
plot(y)

It gives me error when I want to multiply y*time

Anyone know where to go from here?

Best Answer

>> time= 1:1:10;
>> y= 1.2*sin(35*pi*time+2.15);
>> plot(time, y);
