... Unfortunately, the range is infinite, so to use quadl we have to approximate the interval. Note that exp(-35) ans = 6. 3051 167 601 469 89e- 16 which is close to the standard floating-point accuracy, so format ... r3) ans = 1.1102e- 16 ans = -8.8818e- 16 ans = 0 So r1 and r2 very nearly satisfy the equation, and r3 satisfies it exactly. It is easily seen that 16 is a solution. I...
