Give reasons for your answer.
The slopes at each point are independent of y, so the slopes are the same along each line parallel to the y-axis. Note that for y = 10, y' = 0.
o y' = sin(10x) sin(10y)
= 0 on the lines x = 0 and y = 0, and y' > 0 for 0 < x < n/10, 0 < y < n/10.
O The slopes at each point are independent of x, so the slopes are the same along each line parallel to the x-axis. Note that for y = 10, y' = 0.
o y' = sin(10x) sin(10y)
= 0 on the lines x = 0 and y = 10.
o y' = sin(10x) sin(10y) = 0 on the line y = -x + 1/10, and y' = -1 on the line y = -x.
