We are given with the expression <span> (1 - cos x) / (x^2)</span><span> and asked to evaluate the expression to limit as theta approaches zero. In this case, we substitute first zero. cos infinity is 1. The answer is zero over zero. This is indeterminate so we derive the terms according to L'hopital's rule. The derivative is sin x /2x. sin infinity is 1. 1/infinity is equal to zero. Hence the answer is zero.</span>
So from 80 to 64, the change is the difference or 16 books.
now, if we take 80 to be the 100%, how much is 16 off of it in percentage?

Given information
-----------------------------------------------
First showing : 1.30pm
Second showing : 4.15 pm
Inbetween : 1/2 hour break
-----------------------------------------------
Find the time the first showing ends
-----------------------------------------------
1/2 hours before 4.15pm
⇒ 30 mins before 4.15pm
⇒ 3.45pm
-----------------------------------------------
Calculate the duration of the firs show
-----------------------------------------------
1.30pm to 3.30pm = 2 hours
3.30pm to 3.45pm = 15 mins
Total duration = 2 hours 15 mins
-----------------------------------------------
Answer: 2 hours 15 mins
