MATH 112 Lecture Notes - Lecture 3: Sine Wave, Ti-89 Series, Acer Palmatum
Document Summary
At the conclusion of this lesson, students will be able to: Calculate the relative max and min values of trig functions graphically. Then use graphing calcs to sketch using a table of values. f(x) =sinx - 2. Tbl set: tblstart = 0; tbl = 90. The tables provide specific data points to help sketch the curves. f(x) =sinx - 2 g(x) =- 4cos x +1 x. The graphing calc is programmed to find local (or relative) and absolute max and min values. Find one local max of f(x) =sinx - 2. Analyze f(x) =sinx - 2 and g(x) =- 4cos x +1 by stating the amplitude, period, horizontal shift, and vertical shift of each. Solution: f(x) =sinx - 2 g(x) =- 4cos x +1. D. ) let f(x) =a sin(bx - c) +d or f(x) =a cos(bx - c) +d.
