slope 10/5 or 2
<span>first, we are going to define variables as the following:
a = 0
a = π/2
n = 4 rectangles
Δx = [ b - a ] / n ------>Δx = [ π/2 - 0 ] / 4 = π/8
right endpoints :
sum( seq( 4 cos(x) * π/8 , x , 0+π/8 , π/2 , π/8 ) ) = 3.163065 underestimate
left endpoints:
sum( seq( 4 cos(x) * π/8 , x , 0 , π/2-(π/8) , π/8 ) ) = 4.733861 overestimate
the reason because the actual estimate by integral as the following:
π/2
∫ 4cos(x) dx = 4
0</span>
To solve this you need to divided 0.33 in 2. Because 2 meters. So, 0.165 per minute. But the question is per second, so we need to divided 0.165 by 60. In doing that, you get 0.00275 meters per second. For the 2nd question, we do 0.165 multiplied by 3 to get the answer of 0.495 meters in 3 minutes. I hope my answer helps!
