MAT334--Lectures & Home Assignments / small mistake on FE Sample—Problem5

« on: December 06, 2018, 05:27:40 PM »

There is a small mistake on the solution of FE Sample—Problem5
Min Gyu Woo posted the solution and stated,”By Mean Value Theorem, there exists x where 0<x<1 such that h(x)=0”
Actually it is intermediate value theorem.
