MATH 134 -- Problem Set 4 Grading Instructions Section 7.2/On all of these -- give half credit if they just use the table without showing all work and add note: Must show all work for full credit. 11 -- 8 points: 4 for first integration by parts; 4 for second 12 -- 4 points 14 -- 8 points (OK if they either use int ln t = t ln t - t from the table, or integrate by parts twice) 16 -- 4 points 36 -- 6 points (4 for antiderivative, 2 for value) 40 -- 4 points 46 -- 4 points 48 -- 4 points Section 7.3/ 10 -- 4 points (-1 if they miss the 1/3 from the substitution u = 3x) 12 -- 4 points (ditto) 14 -- 4 points (-1 for an arithmetic mistake in coefficients, etc. -3 for using wrong table entry, etc.) 24 -- 4 points (same as 14) 26 -- 4 points (same as 14) 20 -- 4 points (divide first -- note numbering is out of order) 32 -- 4 points (-2 for using #24 instead of #26; explain factorization) 34 -- 4 points (-2 for using #26 instead of #24; show completing square) Section 7.4/ 2 -- 4 points 6 -- 4 points 9 -- 4 points 13 -- 4 points Total: 90 points
