must be entered as
2*x
. The

to indicate multiplication.
Many of these questions require algebraic expressions as answers or exact answers, and must be entered using calculator syntax. For example:
The expression
must be entered as
2*x
. The
*
is
REQUIRED
to indicate multiplication.
The expression
must be entered as
x^2
.
The expression
must be entered as
(x+2)/(x+1)
.
The expression
must be entered as
sqrt(x)
or
x^(1/2)
.
The number
must be entered as
Pi
. For example,
must be entered as
Pi*r^2
.
The answer is case sensitive so x^2 is not the same as X^2 .
The expression
](images/Syntax7.gif){kind=small}
must be entered as
logb(n,x)
. For example,
](images/Syntax8.gif){kind=small}
must be entered as
logb(10,17)
.
Any trigonometric expression, such as
, must have parentheses around the argument.
For any trigonometric expression that is raised to a power, the power is written after the argument of the function. For example,
means
![[cos(x)]*[cos(x)]](images/Syntax11.gif){kind=small}
and must be entered
cos(x)^2
.
