Excellence

A teenager on a couch watching a short film on a phone held sideways

A short film is posted online. $t$ days after it is posted, it is being watched at a rate modelled by

$ \frac{dV}{dt} = \frac{k\ln(t + 1)}{t + 1} $

thousand views per day, where $V$ is the total number of views (in thousands) and $k$ is a constant.

In the first 2 days after it was posted, the film was viewed 30 000 times.

How many days after it was posted had it been viewed 120 000 times in total?

You must use calculus and show the results of any integration needed to solve the problem.

The graph shows part of the curve

$ y = \frac{2x - 1}{x + 1}, \quad x > -1 $

and the line $y = 3 - x$. They meet at the point $P$.

Diagram

You must use calculus and show the results of any integration needed to solve the problem.

Excellence

The graph shows the curve

$ y = e^{\sin^2 x}\sin 2x $

for $0 \le x \le \frac{\pi}{2}$.

Diagram

The shaded region, between the curve, the $x$-axis and the line $x = k$, where $0 < k \le \frac{\pi}{2}$, has area $e^{3/4} - 1$.
