I would simplify the first derivative to:
I was just wondering if somebody could check over my math if they have a second.
Find and find y''(x) @ (5 , 1)
Solved for dy/dx by subtracting and dividing
Took using quotient rule
Plugged in dy/dx to the second derivative At this point does the procedure look correct? I plug in x = 5 and y = 1 and get 1260.
