oh wait equation is messed up lol just asec
 one year ago

DLSBest ResponseYou've already chosen the best response.1
\[\frac{dy}{dx}=\frac{dlog(x^{2}\sqrt{x^{2}+1}}{dx^{2}\sqrt{x^{2}+1}} \times \frac{dx^{2} \sqrt{x^{2}+1}}{d \sqrt{x^{2}+1}} \] ..so on

i do like this,where i didnt diff. wrt. dx
 one year ago

ghaziBest ResponseYou've already chosen the best response.4
you have to differentiate wrt x, you can't diffrentiate wrt to function

wth :/ am i taught wrong :S but i was getting all the answers like this
 one year ago

ghaziBest ResponseYou've already chosen the best response.4
differentiation is done wrt to a variable basically differentiation tells us rate of change of one variable wrt to another and function is something that tells us the relation between those two variables so we can never get rate of change wrt to a function
