Question

A man travelling on f(x, y) = sin(xy). His shadow passing through the origin in a straight line (Sun travels with him overhead). What is the slope of the line traveling on which would lead him to the lowest elevation?​

hi machi what r u doing now

Answer 2

Step-by-step explanation:

Given A man travelling on f(x, y) = sin(xy). His shadow passing through the origin in a straight line (Sun travels with him overhead). What is the slope of the line traveling on which would lead him to the lowest elevation?

• Now a man is travelling on f(x,y) = sin (xy)
• As the sun goes along with him over head the shadow of the man passes through origin in a straight line.
• We need to find the slope of the line that leads to the lowest elevation.
• Now differentiating we get
•   f(x x) = - y^2.sin(xy)
•  f(y y) = - x^2. sin (xy)  
•  f(x y) = -yx.sin(xy)
• sin 0 = 0
• Now (0,0) point does not have any conclusion .
• Since there is no such point  the man will not at all reach the lowest elevation point.
