Question 1014579
*********************************************
3a) ln(x) is defined only for x > 0, hence |x| ensures x > 0
*********************************************
3b) Take the integral
integral 2/x dx
Factor out constants
2 integral 1/x dx
The integral of 1/x is log(x), therefore
Antiderivative of 2/x = 2log(x)+constant where x > or equal to 1
