Misprints in the January 1999 edition of "Linearity"

• Exercise 3.4.7: Delete "dB/dt,".
• Page 173, line 4: "moment's though" should be "moment's thought".
• Page 182 (Sec. 5.1), Example 4: Delete the stray "s" in the last term of the long equation.
• Page 262, example: Every expression for D except the first is missing a factor 3. (Correspondingly, the answer is -69.)
• Exercise 6.2.1: Delete v_3 from the list of vectors.
• Page 255: Change "del" or, more authentically, "nabla" (a Hindi letter). to "del" or, less ambiguously, "nabla". (Reportedly, "nabla" means "Assyrian harp".)
