DEG RAD GRAD Sets the angle mode to degrees, radians, or gradians. NORM SCI ENG Sets the numeric notation mode. Numeric notation modes affect only the display of results, and not the accuracy of the values stored in the unit, which remain maximal. NORM displays results with digits to the left and right of the decimal, as in 123456.78. SCI expresses numbers with one digit to the left of the decimal and the appropriate power of 10, as in 1.2345678105 (which is the same as 123456.78).
Note: In some restricted environments (for example function table, data editor, and the %h menu), the TI-30XS MultiView calculator may display E instead of 10n. ENG displays results as a number from 1 to 999 times 10 to an integer power. The integer power is always a multiple of 3. Note: C is a shortcut key to enter a number in scientific notation format. The result displays in the numeric notation format set in mode. FLOAT 0123456789 Sets the decimal notation mode. FLOAT (floating decimal point) displays up to 10 digits, plus the sign and decimal. 0123456789 (fixed decimal point) specifies the number of digits (0 through 9) to display to the right of the decimal.

Fractions

q %N %j %O In the MathPrint mode, fractions with q can include operation keys (T, V, etc.) and most function keys (F, %_, etc.). In Classic mode, fractions with q do not allow operation keys, functions, or complex fractions in the numerator or denominator. Note: In Classic mode, data editor, and table, use W to perform complex division problems. Calculations using fractions can display fraction or decimal results, depending on input.
The TI-30XS MultiView calculator defaults output to improper fractions. Results are automatically simplified. q enters a simple fraction. Pressing q before or after a number can result in different behavior. Entering a number before pressing q makes that number the numerator. To enter fractions with operators or radicals, press q before you enter a number (in MathPrint mode only). In MathPrint mode, press $ between the entry of the numerator and the denominator. In Classic mode, press q between the entry of the numerator and the denominator. %N enters a mixed number. Press %N between the entry of the unit and the numerator. % O converts between mixed numbers and simple fraction form. % j converts results between fractions and decimals.

Calculators On tests, you may only use one of the following calculators:
TI-30Xa TI-30XIIS TI-30XIIB TI-30XS MultiView TI-30XB MultiView
These are all made by Texas Instruments. None are financial calculators. The proctor will check your calculator before the exam. If you dont have an approved calculator, and cannot borrow one, you will be required to take a make-up exam at a later date, using an approved calculator, and will receive a 10 point penalty. If you are found using an unapproved calculator during an exam, you will get a zero for the exam. Many of the problems in this class can be solved simply with a financial calculator. In this class, you will always be expected to solve the problems using the formulas, not using a financial calculator. On both homework and exams you will be required to "show work" which means writing down the formulas being used. Procedures There will be frequent homework including spreadsheet projects, a midterm test, and a final exam. There may also be some quizzes. For homework, quizzes, and tests, answers are expected to include all the work necessary to do the problem.
Homework and Quizzes Exams Lab Projects Attendance: Required at all talks
15% 50% (2@25 % each) 30% (3% each except for Labs 6 & 7 which are 6% each) 5% (1% each)
All work in this class must be your own. You may discuss the labs with a classmate, but you must complete the lab independently. Copying any portion of someone elses lab, no matter how small the portion, or allowing any portion of your lab to be copied, is considered cheating and will result in an automatic zero on the lab for all parties involved. Academic Adjustments Students who have been certified by the Office of the Dean of Students -- Adaptive Programs as eligible for academic adjustments should go to MATH 242 and request an Information Sheet for this semester that explains how to proceed this semester to get these adjustments made in Mathematics courses. This should be done during the first week of classes. Only students who have been certified by the ODOS-Adaptive Programs and who have requested ODOS to send their certification letters to their instructors are eligible for academic adjustments. Students, who are currently undergoing an evaluation process to determine whether they are eligible for academic adjustments, are encouraged to find out now what procedures they will have to follow when they are certified, by requesting the above mentioned Information Sheet from MATH 242. Large print copies of the Information Sheet are available from MATH 242 upon request.
