Calculus I Homework for Fall 2014
September 17
September 15
September 12 – returned quiz explained one homework problem. Discussed translating graphs and composition of
functions. Discussed how to graph a piecewise function. Homework: Section 1.3 - 29, 3155 – 60, 61, 65, 67, 69, 71, 79,
105 – 110. WebAssign will open later today and will close at 11:59 on Sunday.
September 10 – Returned quiz. New quiz. Discussed domain and range of sinusoids and trig values of any angle [0,2𝜋].
Discussed three types of functions and evaluating functions at “interesting” values. Homework: KNOW trig values for
all familiar angles [0, 2𝜋]. KNOW the domain and range of sinusoids (consequently all trig functions). Section 1-3 – 5, 7,
9, 12, 19, 23, 27. WEBASSIGN is due before midnight tonight.
September 8 – Quiz over homework. Defined a real-valued function of a real variable. Discussed 6 functions – what
their graphs look like, what their domains and ranges are and interval notation. Homework: DEFINE: real-valued
function of a real variable. KNOW the shape of the graph, domain and range of the first 6 functions on page 22. Section
1.3 – 3, 6, 8, 9, 11, 15, 17, 25, 29 and 31. KNOW the trig values associated with the “familiar” angles in quadrant 1 (at
least). Real-valued functions use radian measure. WebAssign is up!
September 5 – Returned homework and discussed errors. Students worked problems about lines and slope.
Homework: Section 1.2 – 5, 10, 12, 14, 15, 20, 21, 23, 25, 27, 29, 34, 40, 45, 55, 60, 65, 75, 79and 93 - 96. (at least. . . if
you need more practice, work odd problems not in the list.)
September 3 – Quizzes from last time were returned and homework was collected. Discussion included finding points of
intersection of two graphs, and how to enter data to calculate regression (predictor) equations. TURN OFF STAT PLOT
before graphing equations. Homework: Section 1.1 57 – 67 odd, and 77 - 80, wise students will read the examples in
section 1.2 before class on Friday.
August 29 – Quiz and homework evaluation. Discussed how to determine intercepts and symmetry for a given equation.
Homework: 20, 21, 24, 29, 31, 36, 44, 45, 50, 51, and 55. On page 3 – complete windows for b, d, and e from the
explorations.
August 27 – Answered syllabus questions and class procedure. Discussed names of sets of numbers. Discussed naming
functions and sketching the graph of a function by point plotting. Homework: READ the syllabus, KNOW the sets
named and what they contain, work problems in Section 1.1 – 1-4, and 7 – 12 by point plotting (graph paper is not
required if you are neat.)
