Math 165 Typing Assignments
Some assignments must be typed.
Microsoft Word
©
and other word processors have facilities for superscripts, subscripts, and fractions. The instructor is using
T
E
X
, a program for typesetting mathematics.
If you prefer, mathematics may be typed as you would enter the information in your calculator.
For example, the sentence
sin
2
(x) + cos
2
x
= 1.
may be typed as
sin^2(x) + cos^2(x) = 1.
The sentence
1
x + h
−
1
x
= −
h
x(x + h)
.
may be typed as
(1/(x+h)) - (1/x) = - (h/(x(x+h))).
Which of the following is correct?
1/(x+h) - 1/x = - h/x(x+h).
1/(x+h) - 1/x = - h/(x(x+h)).
When in doubt, use parentheses
()
.
