You can find guidelines for posting homework on this forum here. If you have trouble with Matlab basics you may consider doing the Onramp tutorial (which is provided for free by Mathworks).

when i have this like problem i use this code:
t=linspace(0,2*pi,50);
f=((t>0)&(t<=1)).*2+((t>1)&(t<=pi/2)).*0.5.*t.^2+((t>pi/2)).*cos(t);
plot(t,f)

Why did you post a complete solution to a homework question?
I would also use ... to make each piece of this function more distinct:
t=linspace(0,2*pi,50);
f= ((t>0)&(t<=1) ).*2+...
((t>1)&(t<=pi/2)).*0.5.*t.^2+...
((t>pi/2) ).*cos(t);
plot(t,f)
