- pg 18 - Exercises 2 and 3. The polynomial should be
F(x) = x ^{3}+x^{2}+x+1 - pg 22 - Example 2.4 should say
- and we construct f(u̅
_{1}, u̅_{2}, u̅_{3}) by blossoming each term:

- and we construct f(u̅
- pg 26 - first sentence of second paragraph is missing the period at the end of the sentence.
- pg 32 - Figure 2.9. Second row from bottom, last node should be labled f*(1̅,δ,δ)
- pg 40 - Both figures:
- left f(t_1,t_2,t) should be f(t_2,t,t)
- right f(t_1,t_2,t) should be f(t_3,t,t)

- pg 50 - Knot vector in paragraph about the Oslo algorithm should not have a minus sign in front of u_4.
- pg 50 - In the paragarph about the Oslo algorithm, only the left edge gives us control points; the right edge does not.
- pg 52 -
*N*should be defined to be 1 if_{i}^{0}(u)*u*(i.e., there should be "<=" on one side of_{i-1}<= u < u*u*and "<" on the other side). - pg 55, 3rd line of first paragraph, "we see the a single..." should be "we see the single..."
- pg 59, end of next to last paragraph. The interval should be
[t _{n-1}, t_{L+n-1}] - pg 65 - two summations at bottom of page - neither
one should have an
