Limit of x - lnx as x approaches infinity: Solving Indeterminate ...
May 11, 2010 · Which might be why you ended up with a value of 0 instead of the right value, which is infinity. It's much simpler to write x - lnx as x (1 - lnx/x), and note that 1 - lnx/x --> 1 as …
Find x for ln x=-2 using the natural logarithm formula
Oct 8, 2010 · To solve the equation ln x = -2, x can be expressed as e^ (-2), which equals approximately 0.135. However, it is important to note that the natural logarithm function is only …
What is the limit of x^lnx as x approaches 0+? - Physics Forums
Jan 22, 2012 · ln(x^lnx)= lnx*lnx. To apply L'Hospitals Rule I have to have it in quotient form, so I rearranged my equation to lnx/ (1/lnx). After taking the derivative of both I ended up at -(lnx)^2. …
