s=1.25;
t1=0:0.01:pi/2;
t2=pi/2:0.01:pi;
t=[t1 t2];
p1= 4*(sin(2*t1)).^2.*exp(-t1/s).^2 + 2;
p2= 4*(sin(2*t2)).^2.*exp(-t2/s) + 2;
[~,i1_min] = min(p1);
[~,i1_max] = max(p1);
[~,i2_min] = min(p2);
[~,i2_max] = max(p2);
figure()
hold on
plot([t1 t2],[p1 p2])
plot(t1(i1_min),p1(i1_min),'o',"Color","r")
plot(t1(i1_max),p1(i1_max),'o',"Color","r")
plot(t2(i2_min),p2(i2_min),'o',"Color","r")
plot(t2(i2_max),p2(i2_max),'o',"Color","r")
hold off
