[SOLVED] differentiating [ sin(1/ln(x)) / x ].. solution?
hello all. I do not have the solution to this question that I am about to ask. But if you find the time, try this solving this problem and feel free to type your answer and compare with mine.
differentiate :: sin(1/ln(x)) / x
my answer: -[ ( (sin(1/lnx)*(ln(x)^2) + cos(1/ln(x)) ) / ( (x^2)*(ln(x)^2) ) ]
i am extremely curious about what you all got. I want to see if i did it correctly. Thanks in advance.
I found some time to find the d^2y/dx^2 of this f().
answer #2 for d^2y/dx^2 : { [ (cos(1/lnx))(2+4lnx+2(lnx)^2+(x^2)(lnx)^3) ]+[ (sin(1/lnx))* (lnx) * (4(lnx)^2 - x^2+2(lnx)^3) ] } / { [(lnx)*x]^3 }
woah, i spent so much time doing it.. if you guys have a time to do it, post your answer pls! thanks again.
