This booklet presents somebody wanting a primer on random signs and methods with a hugely available advent to those topics. It assumes a minimum volume of mathematical heritage and specializes in strategies, comparable phrases and engaging purposes to quite a few fields. All of this can be stimulated by means of various examples applied with MATLAB, in addition to numerous workouts on the finish of every bankruptcy.

SOLUTION: (a) Because Maple follows the order of operations, (-27/64)ˆ2/3 ﬁrst computes (−27/64)2 and then divides the result by 3. > (-27/64)ˆ2/3; 243 4096 22 Chapter 2 Numbers, Expressions, and Functions (b) On the other hand, (-27/64)ˆ(2/3) raises −27/64 to the 2/3 power. Maple does not automatically simplify − 27 64 2/3 . > (-27/64)ˆ(2/3); √ 1 3 (−27)2/3 64 64 However, when we use simplify, Maple returns the principal root of 2/3 − 27 64 . > simplify((-27/64)ˆ(2/3)); √ 9 1+i 3 64 2 To obtain the result − 27 64 2/3 = 3 −27 64 2 = − 3 4 2 = 9 , 16 which would be expected by most algebra and calculus students, we use the surd function: ⎧ ⎨x1/n , x≥0 surd(x, n) = .
Whenever possible, Maple gives an exact answer and reduces fractions. 1. 2. 3. 4. 5. Maple follows the standard order of operations exactly. “a plus b,” a + b, is entered as a+b; “a minus b,” a − b, is entered as a-b; “a times b,” ab, is entered as a*b; “a divided by b,” a/b, is entered as a/b. Executing the command a/b results in a fraction reduced to lowest terms; and 6. “a raised to the bth power,” ab , is entered as aˆb. 19 20 Chapter 2 Numbers, Expressions, and Functions When entering commands, be sure to follow the order of operations exactly and pay particular attention to nesting symbols (parentheses), multiplication operators (like * and the noncommutative multiplication operator, &*), and the exponentiation symbol (ˆ).
To delay the evaluation of g(x) enclose g(x) in single quotation marks, ’. 12); gives us the plot of g(x) shown in Figure 2-1. 2 0 0 Figure 2-1 2 4 6 x 8 10 12 Plot of a recursively deﬁned function We will discuss additional ways to deﬁne, manipulate, and evaluate functions as needed. However, Maple’s extensive programming language allows a great deal of ﬂexibility in deﬁning functions, many of which are beyond the scope of this text. 3 Graphing Functions, Expressions, and Equations One of the best features of Maple is its graphics capabilities.
