MATH 186 – WINTER 2009 HOMEWORK SET 7 Due Friday 03/20 Be kind to your grader, please staple your work! Notice it’s a two-page homework! What you need to know: - Techniques of integrations: by parts, substitution, and partial fractions - Improper integrals - Taylor polynomials - Vector spaces. What you shouldn’t forget: - Definition of integrable function - Linearly independent vectors and bases. Ex 1. Prove that the improper integral Z 1 2 x + 1 x 2 (1 + x 2 ) dx exists and it’s finite. Compute it explicitly. Ex 2. Let P 3 be the vector space of the polynomial functions of degree
