Read 3.1; Formality of the page 134 rules will not be emphasized, but the conceptual introduction in previous pages is helpful, and you still need to understand all examples.
3.1; 9, 10, 11, 12, 21, 22.  (On 21 & 22 and throughout Calculus, you must use Radians.)
On all that follow, use good notation to show steps or explain reasoning; just an answer will not suffice.
3.1; 38, 41, 45, 61, 79, 95, 96(Do you need to know constants are positive?).
