| Anagram 03/09/17 10:02:40 AM #1: | More specifically, I don't understand how the computer got a result. Find dy/dx by implicit differentiation. Now I can easily tell that this becomes (1/2)*7x^(-1/2) + (1/2)y^(-1/2)*y' = 0. All of that is easy and makes perfect sense. My problem is this next part. The computer goes from the result I got to this: 1/radx + y'/7rady = 0 I can see that the x^-1/2 and y^-1/2 are becoming the radicals in the denominators, sure, but the rest is a mystery to me. Where did the 1/2 in both the x and y parts go? How did the 7 get from being in front of the 7 to being in front of the y? --- Not changing this sig until I decide to change this sig.
