Question

(b) Figure Q2(b) illustrates the 3D topography of a land plot to be developed. Based on computer modelling, the original terrain could be represented by the following equation

? = x^4 + x ln y + sin x,

where x is horizontal distance at x-direction, y is horizontal distance at ydirection, and z is ground level.


(i) Compute the slope equation of the terrain at x and y direction.

(ii) Evaluate the slope of x and y direction at coordinate (4, 5).
