Paste your code as text and format it with the "Code" button instead of as image...
But, you are missing the difference between array and element-wise multiplication. See the times, .* documentation for all the info...the "dot" operators are key.

s = 1.25;
t1 = 0:0.01:pi/2;
t2 = pi/2:0.01:pi;
t = [t1 t2];
p = [(4*(sin(2*t1))(sin(2*t1)))*exp(-(t/s)(t/s))+2) (4*(sin(2*t2))*(sin(2*t2)))*exp(-t2/s)+2)];
figure()
plot(t ,p)
xlabel("yura")
ylabel("elad")
title("lauren hazout")

That's better, thanks, but why not edit the original Q? and put the code there? Will it not let you edit your own Q?.
But, you've not taken the advice to heed -- the problem is still that you're not using the "dot" operators...

As the error suggests, use element wise powee .^
