General guidelines for working with math answers
▪ 
Basic editing  To edit, select the Undo
,
Redo
,
and Reset
tabs, as needed. You can also cut, copy, and paste
using standard keystrokes. (More
info on selecting/editing) 
▪ 
Navigating within expressions  Press the
arrow keys from your keyboard. 
▪ 
Type
*
for the multiplication operator.
Do NOT use the
letter x. Enter multiplication explicitly,
that is, type 2*a*b,
not 2ab.
Use
scientific notation, not e (which
MasteringPhysics evaluates as a variable). For
example, enter 1.23*10^5 instead of 1.23e+5. 
▪ 
Use commas only as separators between multiple
expressions within a single answer box, such
as “1999, 2009”. Do NOT use commas in any large
number, such as 32000. 
▪ 
Order of expressions can affect grading  If
a question asks for several answers in a particular
order, such as numeric order, your answers must be
in that order. (MasteringPhysics uses string
matching to grade such answers.) 
▪ 
No spaces  The answer box does not allow you
to enter spaces. 
▪ 
No units  The units part of the answer is
provided outside your workspace, so you don’t have
to enter this.

About the
arguments of special functions:
▪ 
The argument of a function
can be a number, variable, or
more complicated math
expression. 
▪ 
IMPORTANT:
All arguments of
trigonometric functions must be
in radians, not degrees. That
is, if a question asks you to
find the xcomponent of a vector
of length 10 at 30 degrees above
the horizontal, MasteringPhysics
will accept "10*cos(/6)",
but not "10*cos(30)".
