Can someone help me out with this questions? I am completely lost.
A) If y=ln{x+(x^2-a^2)}, evaluate dy/dx, expressing your answer in its simplest form.
Show that (x^2 - a^2) d^(2)y/dx^2 +x(dy/dx)=0

check your original log function and the conclusion you're supposed to reach ... as you've written it, it doesn't work.
With all do with respect, can you show the final answer. As you were saying, the problem is written down incorrect. R u trying to tell me that there is no solution, but if there is can you finish for me. i would appreciate it!!!

Thats part of my homework assignment. Its in my calculus book.
Look, there's a problem with the question as posted. This has been said several times now. Sorting out this problem is not our job. It's your teacher's job. So speak to your teacher.
Skeeter your right!!!! It cant be solve. Doesnt equal zero. the professor tried to solve to zero, its not possible. My professor is wrong. Anyway thank you for you help.
