We are given statement " John read the first 114 pages of a novel, which was 3 pages less than 1/3 of the novel".
Let us assume total number of pages of a novel = p pages.
3 less than 1/3 of total pages = 114.
3 less then 1/3 of P is = 114.

<h3>Therefore, required equation for number of pages of a novel is </h3><h3>

Remember that cos(0) represents the x value of a point on the unit circle. The period for the unit circle is 2π in radians which means that adding or subtracting 2π will get you back to the same point which has the same cosine.
Examples: cos(2π),cos(100π),cos(60π)
