clear;clc;
Vm =1 ; % Amplitude of signal T= 1 ; % Period
syms t; 
v1 = Vm*sin((4*pi*t)/T); 
v2= 2*Vm*sin((4*pi*t)/T); 
v = piecewise(0<=t<=T/2,v1,T/2<=t<=T,v2);
figure; 
fplot (t,v) ; 
grid on xlabel('time s '); 
ylabel('Voltage V '); 
title('v(t) vs t '); 
legend('v ')

Original question in case dummy erases this one too:
