We can use t =. or Clear[t] to remove the value assigned to t: In[3]:= t =. 7 Standard Computations Mathematica can do standard computations just like an electronic calculator. 0094 NumberForm@expr, nD prints expr with all approximate real numbers showing at most n sig- nificant figures—that is, at most n-digit precision. 37114 × 10-3 24 Chapter 2 Interactive Use of Mathematica ScientificForm@exprD prints expr with all approximate real numbers expressed in scientific notation. 4 × 10 -3 ScientificForm@expr, nD prints expr with all approximate real numbers expressed in scientific notation showing at most n significant figures—that is, at most n-digit precision.

Since sqrt has not been defined, Mathematica returns the input unevaluated. 6 Ways to Refer to Previous Results One way to refer to previous results is by their assigned names. We can assign values to variables with the operator “ = ”: variable = value For example, we can assign a value to the variable t: In[1]:= t = 3 + 4 Out[1]= 7 The variable t now has the value 7: In[2]:= t + 2 Out[2]= 9 To avoid confusion, names of user-created variables should normally start with lowercase letters because built-in Mathematica objects have names beginning with capital letters.

Sending another input to the kernel restarts the kernel and begins a new Mathematica session. 7 PROBLEMS In this book, straightforward, intermediate-level, and challenging problems are unmarked, marked with one asterisk, and marked with two asterisks, respectively. For solutions to selected problems, see Appendix D. 1. 2. 5. , access information on the built-in function RSolve. 16 Chapter 1 The First Encounter Answer: RSolve[eqn, a[n], n] solves a recurrence equation for a[n].
