for part b yes that's what i mean. for part a.. i dnt get u? as i said above the differential of a ln(f(x) = 1/f(x) * f ' (x) is that what u did?
idk what LaTeX is...
Homework Statement
a) if f(x)= ln(x/√(a-x^2)) show that f'(x) = a^2/x(a^2-x^2)
[b] ∫1/x(25-x^2) dx
The Attempt at a Solution
for a) i tried differentiating the top (ans. = 1) then the bottom.. obviously the bottom's where hte prob is at lol.. i kno d/dx ln[f(x)] --> 1/(f(x) χ f...
