2.The line meets f(x) at x = 0 and x = 10.
f(0) = 3 sin(0/2π) + 2 = 2
f(10) = 3 sin(10/2π) + 2 = 4.999
The line passes through (0, 2) and (10, 4.999).
Slope of the line
= (4.999 - 2)/(10 - 0)
= 0.30

A little confusing as the axes should be t and f(t).
Anyway, when t = 0 we have:
f(0) = 3sin(0/2π) + 2 = 2
Also, f(10) = 3sin(10/2π) + 2 = 5
Examining the gradient of (0, 2) to (10, 5) we have:
(5 - 2)/(10 - 0) => 3/10 = 0.30
