Hey all how would this be coded?

For a period of 10 seconds and an amplitude of 1 meter, develop a variable that consists of a sine wave of 2 periods where data are determined every tenth of a second.

i have an idea like this

t = [0:1/10:10];

y = 2*sin(t);

plot (t,a)

But I dont know if that is corrent

For period of 10 seconds, f =1/10 or f=0.1 in the above equation.

Since you want to plot a sine wave of 2 periods in a time of 10 seconds, the time period of sine wave must be 5.

freq = 1/5;

sineWave = sin(2*pi*freq*t);

As amplitude required is 1, you need not multiply the sine wave with any coefficient. Hence, sineWave variable defined above is suffice. You can plot it as

plot(t,sineWave)
