(b) Using points on the curve at t = 0.0 s, t = 0.5 s, and t = 1.0 s, use the trapezoidal method to calculate the total number of photons emitted between t = 0.0 s and t = 1.0 s. Is this an overestimate or underestimate of the exact number? Explain your answer - you may find it helpful to illustrate by annotating the figure above part (a).The gure below plots the bioluminescence model photon emission rate curve R(t) = At2 exp(Bt), where A and B am constants, and t is the time in seconds, for the numerical values of A = 2.802 X 101 and B = 4.30. m ox N O , Photon emission rate R(t) (108 5'1) J) o o P m H o 1.5 2.0 25 3.0 Time t (s)
