1. Do you know the taylor series of ln (1+x) ? That would help.

2. Come on mate you can do this one. Don't let the absolute value scare you, just replace it with its piece wise definition! If x > 0, |x| = x. If x < 0, |x| = -x and if x=0, |x| = 0.

Find the derivative for the two separate pieces. Find the correct derivatives (check your working again), then set them equal to 0 for the extreme points and solve.

so i make two separate equations and solve them
is there a chance that one of them will cancel out??

 

[Gib Z]

Not two separate equations, just a single function that defined in terms of TWO pieces.
