(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

g(x)=x - sin (pi*x) at [0,2]

2. Relevant equations

all values where g'(x)= 0 (or non-existant) are critical points

3. The attempt at a solution

g'(x)=1 - ╥(cos(╥X))

1/╥=cos(╥X)

cos^(-1) (1/╥) = ╥X

X=(cos^(-1) (1/╥))/╥

x=.397 and x=? 2nd point
