In the last question, why did we take x as constant and take partial with respect to z? Instead, couldn't we take z as constant and take partial with respect to x? Since the values of x and z are equal at that point, the result is the same, but what if it were different? How can we understand whether the slope in the y direction is according to z or x?
Thank you from a Chinese student !
