CourseWare account: Sign up for a CASA account on CourseWare at www.casa.uh.edu. CASA refers to the CourseWare website, tutoring center and testing center (located on the second floor of Garrison Gym). If you have not taken a math class that uses CASA before, you need to setup your account. If you have already setup a CASA account for another math class or the placement exams, you do not have to create another account. Just login after classes start and you will have access to any CASA courses for which you are enrolled. If you have a problem registering with CASA, first make sure that you are enrolled (you cannot get an account if you are not enrolled), then click on the Contact us link on the CASA webpage. If nothing else works, go to 221 Garrison gym. You should setup your account right after the first class session. Late CourseWare registration may result in grades being lost! You will use your CourseWare account to see your grades and to opt out from the final exams. Online quizzes: There will be online quizzes on the online assignments tab of your course site on CourseWare. All the 13 quizzes, including course policy quiz are already uploaded on the CourseWare. You may start working on them as soon as we cover the material corresponding to a quiz in class. You may take each quiz up to 20 times; your highest score for the period will be the grade recorded for the quiz. You must wait 10 minutes between attempts. You may get help with your quizzes in CASA. There will not be an amnesty period at the end of the semester on quizzes. Once a quiz is expired, it is over for the semester. Please make sure that you complete each quiz before the deadline. No quiz scores are dropped. You need to score 100% on the course policy quiz to gain access to other quizzes.
Daily in class poppers: Daily in class poppers will be given in each class starting the 3 rd week of classes. Questions on poppers are multiple choice. There are NO makeups for the poppers; 15% of the total number of poppers given during the semester will be dropped. Your lowest grades will be considered for the purpose of dropping poppers. It is student s responsibility to bubble in the information carefully and completely. Incomplete, misbubbled or illegible forms will not be graded. Popper forms are sold in the book store and they are section specific. Make sure to check your curse number (Math 1311) and section number (17839) on the poppers before you buy them. If you change sections, you must buy forms for your new section. Use a #2 pencil to fill out the forms. Poorly erased marks or marks made using anything other than #2 pencils can cause your form to be rejected or cause the mark reader to incorrectly mark your question wrong. The mark reader is also sensitive to wet, torn or damaged forms and may not grade them correctly. Poppers WILL NOT be returned to the students and will be shredded after scoring. Homeworks: Homework assignments are available on the curse website together with the instructions on how to submit the assignment. Tests: There will be test reviews before each exam. All exams are in CASA Testing center. See the calendar for the exam dates. You need to schedule your test (except for final exam) on CourseWare. Scheduler on CourseWare opens around two weeks before the exams.
Make sure to schedule your test as soon as the scheduler opens by going to the proctored exams tab on CourseWare. There will be NO makeups for the tests. Your final exam grade will be used to substitute any missed test grades or the lowest test grade. Missing more than one test will result in a 0 for the second (and any subsequent) test grade. Final: Final is mandatory and comprehensive unless you are eligible to OPT OUT. OPT OUT: At the end of the semester if your grade is 80% or higher, you may choose not to take the final and keep your current grade as your grade for the course. If your grade is below 80%, you MUST take the final exam. Extra credits: A practice test and practice final will be available on your CourseWare account prior to each test and final exam, respectively. There will be 20 attempts for the practice test/final. Highest score will be recorded. 10% of your highest practice test/final score will be added to your test/final score. There will be NO makeups or extension on the practice tests/final. Tutoring help: Go to CASA tutoring center (222 Garrison gym) anytime when it is open, to get help from the tutors. Go to CASA tutoring center (222 Garrison gym) on Wednesday 12:00 PM 2:00 PM, during my office hours, to get help from me.
Accommodations for students with disabilities: A current Student Accommodation Form (SAF) must be presented in a timely manner for accommodations to be approved. In order to take tests at CSD, a current valid RITA form must be presented. A reservation made at least 48 hours in advance is required to take a test at CSD.
Quiz 0 Calculator skills Calculator review: Some symbols to keep in mind: 1. ^ is called the caret symbol. It is used to raise a number to certain paper. Example: 4 3 = 4 4 4 = 64
2. π = 3.14159 This is called pi 3. e = 2.71828 This is called the exponential function
Some rules to keep in mind: Rounding Unless otherwise mentioned, round to 2 decimal places. Round down for 0-4. Example: 3.14267 Round up for 5-9. Example: 3.14627 PEMDAS P: Parentheses E: Exponents M: Multiplication D: Division A: Addition S: Subtraction Example: (7*3^-2+1)/(3-2^-3) To let the calculator know that a group of numbers all go together, we use parentheses. Examples: (2 3 + 0.5)/40
Types of interests: Simple interest wait until the end of the loan before calculating or paying interest. Amount = (Principle) + (Principle) (interest rate) (time) A = P(1 + rt) Compound interest at certain time periods the interest you have incurred is calculated and added to your debt. (More commonly used banks use compound interest.) Compounded yearly. A = P(1 + r) t Compounded monthly. (Automobile loans and home mortgages) Monthly interest rate, r = APR 12 APR Annual percentage rate A = P (1 + APR 12 )12t, if the time t is given in years. Example 1: If you borrow $5000 from a bank that charges at interest rate 7%, how much money will you owe after 10 years? A. Simple interest:
B. Compound interest (compounded yearly): C. Compound interest (compounded monthly):
Scientific notation: Used to express really small or really big numbers 4.2 10 8 = 4.2 10 8 = En means to move the decimal point n places to the right. E n means to move the decimal point n places to the left. Examples: 2.98 10 25 = 2.98E 25 = Examples: 1. If the equation for present value of an annuity is given by PV = A [ 1 (1+i) n ], where A = 2000, i = 0.13, n = 36. What is the i 4 correct way to input this in the calculator to solve for P? 2. If I want to evaluate 6+e+1 2, and I input 6 + e + 1/2, into the calculator, then what is my mistake?
3. If I want to evaluate 73.2 6, and I input (7^3.2 6)/( 2 + 4) into the 2+4 calculator, what is my mistake? 4. What is the value of ( 4+π 4 9 )6+ 8? 5. What is the value of 7.6 7.8+e 6.5? 6. Evaluate the value of A A+ B using A = 17 and B = 30.
