The initial scenario is a specific case of the subsequent one, so we will address the second case first.
Consider . Through the utilization of derivatives and trigonometric function properties, it is determined that
The equation is represented as . It's important to note that since
it leads to the equation
,
which signifies that . Consequently,
It's notable that in this instance, the value of k is independent of A and B. Thus, it applies universally to any values of A and B. The first scenario is included since it corresponds to A=0 and B=1.
Indeed, a fare of $40 is a fair charge for the cab ride.
