Question 69

The telemetry system of a satellite records its pitch angle deviation (in degrees) from its target orbit at eight consecutive checkpoints in a one-dimensional array:


$- 0.15$	$0.42$	$- 0.88$	$1.12$	$- 0.04$	$0.67$	$- 0.23$	$0.05$

State why a binary search algorithm cannot be used to locate a specific pitch angle deviation in this array.
