This is not twitter: no # before the tags.
The questions sounds like a homework. Then the forum will not solve it fr you, because this would be a drawback for your success.
Please post, what you have tried so far and ask a specific question to your code. You will need 1 line of code only and the commands: plot, sin, cos. With a:b:c you create a vector from the value of a in steps of b until c.

U mean x=0:1:3; y=sin(x); stem(x,y);is it crt. I want discrete so I am using this stem fn. @jan

0:1:3 is [0,1,2,3]. This is less than 4 cycles. 4 cycles mean:
x = 0:0.1:8*pi
stem() is working. plot(x,y, '.') is an option also.
