Simple Calculus Question: Differentiating Square Root Fraction

[QUOTE="rock.freak667, post: 4482214, member: 87212"] Yes well the main point was that for x>0, |tanx| = tanx so it would cancel out to give you sec[SUP]2[/SUP]x. The only reason I can think of to specify something like that is if you accounted for taking the square root of the radical. Meaning that your expression would simplify to √(tan[SUP]2[/SUP]x) = ± tanx and d/dx(± tanx) = ± sec[SUP]2[/SUP]x [/QUOTE]
