You tell her that all of the following are true, EXCEPT "the access time of memory is slow compared with that of storage devices".

Explanation:

A computing hardware utilized to indefinitely or temporarily store data, this device may be outer or inner to a computer, server, and other computing systems, hence common as a storage device. The memory is generally read-write random-access memory provided by semiconductors, typically Dynamic RAM or other types of fast yet temporary storage in the contemporary usage. While storage comprises of storage devices and their media that are not directly available via the processor (secondary or tertiary storage), usually hard disk drives, optical disk drives, and other devices that are slower than RAM but non-volatile.

In polar coordinates, we have

$x=r\cos\theta\implies\cos\theta=\dfrac xr$
$y=r\sin\theta\implies\sin\theta=\dfrac yr$

From this we can write

$\tan\theta=\dfrac{\sin\theta}{\cos\theta}=\dfrac{\frac yr}{\frac xr}=\dfrac yx$

If $\theta=\dfrac{4\pi}3$ , then $\tan\theta=\sqrt$ , so we get

$\dfrac yx=\sqrt3\implies y=\sqrt3\,x$
