Question

Here is an annoying one, lets see who can shine light on this:
$$\huge \frac{ d }{ dx }(\frac{1}{(10-P)})$$
I am well aware that it's meant to be Ln as the answer, but I want to see if anyone runs into the issue I did

ray10 · Answer

$$\large -\ln(P-10)+C$$
is what I get

gorv · Answer

if u integrate it than d/dx will vanish and ln will not come in picture

anonymous · Answer

is there any reason why you obtained -ln(P - 10) + C?  if P is a variable, why not use quotient rule ?

ray10 · Answer

Integrate it you say, hmm but then what will I get?
I shall try the quotient rule now then
well I saw it as 1/x

ray10 · Answer

then I get $$\large \frac{-1}{(p-10)^{2}}$$
