Bahasa Melayu
Rajah 5 menunjukkan sebahagian daripada lengkung $y = \dfrac{8}{x}$ dalam sukuan pertama. Garis $y = h(x)$ yang dilukis pada paksi yang sama ialah normal kepada lengkung ini pada titik $P$.
Dengan menggunakan prinsip pertama, cari $\dfrac{dy}{dx}$ bagi lengkung itu dan seterusnya nyatakan nilai $\dfrac{dy}{dx}$ pada titik dengan keadaan $x = 1$.
Dengan menggunakan prinsip pertama, cari $\dfrac{dy}{dx}$ bagi lengkung itu dan seterusnya nyatakan nilai $\dfrac{dy}{dx}$ pada titik dengan keadaan $x = 1$.
English
Diagram 5 shows part of the curve $y = \dfrac{8}{x}$ in the first quadrant. The line $y = h(x)$ drawn on the same axes is the normal to this curve at the point $P$.
By using first principles, find $\dfrac{dy}{dx}$ for the curve, and hence state the value of $\dfrac{dy}{dx}$ at the point where $x = 1$.
