Okay so the problem is already solved , but how on earth are they getting the values in the second step? (how did the asnwer get -2.829)

Find the average velocity during each time period. s = s(t) = 3 sin(nt)+
2 cos(Tt).
(i) On the interval [1, 2], Vavg
s(2)-s(1)
2-(-2)
— 4.00 ст/s.

(ii) On the interval [1, 1.1], Vavg
s(1.1)-s(1)
-2.829-(-2)
0.1
-8.29 cm/s.
