hello again
you have to change the range of t2 and t3 from 0 / pi to 0 / 2*pi (btw they are identical so you could simply use one variable and not two) , like :
t3 = linspace(0,pi,1000); => t3 = linspace(0,2*pi,1000);

hello
either you swap x and y data in your plot calls , or use view :
figure(1),plot(sin((0:0.1:3*pi)))
legend('original data')
figure(2),plot(sin((0:0.1:3*pi)))
legend('rotated graph')
view([90 90])
