Intro. to Mathcad
This is a very brief intro to using Mathcad (originally written in Mathcad IV) by
someone
who is not an expert.
The following assumes that you have successfully opened Mathcad.
Read the
commentary and see if you can reconstruct the "math" that immediate follows.
The Mouse, Basic Arithmetic and Basic Editing
:
Using the mouse, click at any location in the blank screen.
Then type
3+5=
.
Mathcad should immediately give you the value of
3+5
.
Move to other locations either
using the mouse or just pressing
Enter
and try some other basic arithmetic formulas, as
illustrated just below.
(Notes: to multiply, use the "star" symbol  shift 8; to divide, use the
slash symbol, /; to raise a number to a power, use the ^ symbol  shift 6)

To modify an existing formula, just click the mouse when the cursor is inside the formula
you want to change.
Try it.
You should get a vertical bar (If you get a "box" surrounding part
of the formula, just press the down arrow a few times).
Use the left and right arrow keys to
move around in the formula.
Add stuff by just typing it in, and remove stuff using either the
delete or the backspace key.
Try to figure out what the space bar and the up and down arrow
keys do.
Now position the cursor outside of one of your equations, hold down the left mouse button
and "drag" the cursor over the equation and release the mouse button.
The equation should
now be surrounded by a box.
You can move the contents of such a box by positioning the
cursor in the box, holding down the left mouse button and dragging the box to its new
location.
Try it.
You can also delete every thing in the box using
edit / delete
.
edit / cut
, edit / copy ,
and
edit / paste
also work on these boxes.
Assigning Values and Functions
A few symbols already have values assigned.
Type
e=
.
Now type
controlp=
(this
gives you
pi) (Note: the displayed precision can be changed in the
Fo
rmat / Number
menu, and the font size for variables and constants can be changed in the
Fo
rmat /
Equation
menu)

To assign a value to a symbol, type
symbol
:
value
.
Mathcad will replace the colon,
"
:
", with a "set equal to" symbol, "
