TI-83 in Calculus
Do not become
on your calculator. It's a very useful tool for complicated
calculations, but you should be able to do the basic computations
in calculus without a calculator--or, at most, just using it to
out with tedious arithmetic. Calculators may or may not be allowed on
in particular courses: check with your instructor about the course
Generally, calculators with a built in CAS (Computer Algebra System)
allowed on tests and quizzes.
dependent on your calculator if, for example:
use a calculator when you need to know sin(pi/6) or tan(pi/3) or
use a calculator to get answers in calculations such as 4/7 + 3/8,
can be easily done by hand. Finding (approximate) decimal answers
of exact fractions in relatively simple problems generally means that a
student uses the calculator too much.
don't know the appearance of simple graphs like y=(x-1)^2, y=cos(2x) +
1, y = 2^(-x), etc. without having your calculator graph them.
find yourself immediately punching buttons on the calculator as soon as
you get started on a test. Generally, not very many problems on a
calculus exam will genuinely require a calculator.
