#1. LRAM = .5(f(0) + f(.5) + f(1) + f(1.5)) = 2.605 (roughly, depending on where you rounded)

RRAM = .5(f(.5) + f(1) + f(1.5) + f(2)) = 2.97

MRAM = .5(f(.25) + f(.75) + f(1.25) + f(1.75)) = 2.8


#2. TRAP = .25(f(0) + 2f(.5) + 2f(1) + 2f(1.5) + f(2)) = 2.788


#3. LRAM = .2(f(0) + f(.2) + ... + f(1.4)) = .2(1 + 1.4 + ... + 1.6) (you get the idea...)

RRAM = .2(f(.2) + f(.4) + ... + f(1.6)) = .2(1.4 + 1.6 + ... + 1.4)

TRAP = (LRAM + RRAM) / 2 -OR- .1(f(0) + 2f(.2) + 2f(.4) + ... + 2f(1.4) + f(1.6))
