Prerequisites: A thorough understanding of Calculus and one of 217, 312, 412.

Course Description: This course has two complementary goals: (1) a rigorous development of the fundamental ideas of Calculus, and (2) a further development of the student's ability to deal with abstract mathematics and mathematical proofs. The key words here are rigor and proof almost all of the material of the course consists in understanding and constructing definitions, theorems (propositions, lemmas, etc.), and proofs. This is considered one of the more difficult among the undergraduate mathematics courses, and students should be prepared to make a strong commitment to the course. In particular, it is strongly recommended that some course which requires proofs (such as Math 412) be taken before Math 451.

Textbook: Kenneth A. Ross, Elementary analysis: the theory of calculus. Springer, Corr. 10, 1998. ISBN: 9780387904597. The course covers most of the material in the book except the starred (optional) sections, in the following order (tentative): 1 - 20, 28, 29, 32 - 34, 23 - 26, 31, concluding with a full week of review.

• Homework (25%). Will be assigned every class. Due every Friday before class. One homework with the lowest score will be dropped. Scroll down to see the homework. (20%). October 26, in class. Covers the material in Sections 1 - 12 that we covered in class. Books and calculators are allowed. Solutions. (20%), take-home. Due November 21 at the beginning of class. Solutions. (35%). Friday, December 16, 1:30 - 3:30 pm, in class. Covers the whole course. Books and calculators are allowed. Solutions.Warning: Statement of Problem 3 is false.

Missing/late work: Missed exams - there will be no make-up for the exams for any reason. A missed midterm exam counts as zero points, with the following exception. If you miss a midterm exam due to a documented medical or family emergency, the exam's weight will be added to the weight of the final exam. Late homework (and late take-home exam) can not be accepted. In extenuating circumstances, you may e-mail me your scanned or typed homework (as a single pdf file) on the day when the homework is collected by 8:00 p.m.

Lecture Schedule and Homework: It is a useful practice to read ahead the sections to be covered. Solutions are posted for some (but not all) homework problems. Please come to the office hours to discuss other problems.

## Mathematics - Class 5 / Grade 5

Till now we have learned various types of measurement such length, weight, capacity and time. But none of these measurements can be used to find how hot or cold any object is.

When we touch any hot or cold object, we can make out which is hot and which is cold. But the question here is how much cold or how much hot. At the same time, it is difficult to know the exact level of hotness or coldness by touch because the sense of touch varies from one person to another. To find exact answer, we need some measure of hotness or coldness.

Temperature is the measure of the hotness or coldness of an object with reference to some standard value. The instrument which measures the temperature of body is known as thermometer.

Each thermometer has a scale. Two different temperature scales that are commonly used are:

The Fahrenheit scale is marked from 32° F to 212° F. 32° F indicates the freezing point of water and 212° F indicates the boiling point of water.

Celsius scale is also called centigrade scale and is marked from 0° C to 100° C. 0° C indicates the freezing point of water and 100° C indicates the boiling point of water. Comparison of two scales Conversion of Temperature

When the temperature is given in degree Celsius:

Step 1: Multiply the given temperature in degree by 9

Step 2: Divide the product obtained by 5.

Step 3: Add 32 to the quotient obtained in step 2 to get the temperature in degree Fahrenheit.

Here given temperature is 55° C.

To convert into degree Fahrenheit first multiply 55 by 9 and we get product as 495.

Then, divide 495 by 5 and answer we get is 99.

Now, add 32 to 99 and final answer we get is 131.

When the temperature is given in degree Fahrenheit:

Step 1: Subtract 32 from the given temperature in degree

Step 2: Multiply the difference obtained from step 1 by 5.

Step 3: Divide the product obtained from step 2 by 9 to get the temperature in degree Celsius.

Here given temperature is 90° F.

To convert into degree Celsius first we need to subtract 32 from 90 and we get 58.

Then, multiply 58 by 5 we get answer as 290.

Now divide 290 by 9 and we get answer as 32.2. A medical thermometer, also known as a clinical thermometer is a thermometer used to measure body temperature. Most of these thermometers have both the two scales, Celsius scale and Fahrenheit scale. The scale runs from 35 degree Celsius to 42 degree Celsius.

The temperature of a healthy human body is approximately 37 °C or 98.6 °F. The tip of the thermometer is inserted into the mouth under the tongue or under the armpit for a minute. Then, the number against the point at which the mercury column stops rising further indicates the body temperature of the person.

## Mathematics– Class 2 / Grade 2

Many times we use picture or symbol to represent quantities of objects. Such representation is called pictograph. Pictograph makes information easy and clear to understand. Information that we collect is called data.

Example 1: Aditya decided to conduct a study on most popular car color. So he stood outside his house and recorded the observation about 50 cars passed from there.

This was what he observed. Q1. How many cars did Aditya count?

Q2. How many blue cars did Aditya count?

Q3. How many green cars did Aditya count?

Q4. What is the most popular color car according to his observation?

Q5. What is the least popular color car according to his observation?

Example 2: Ria interviews 20 people and asks them which ice-cream flavor is their favorite. She made a pictogram with the details she gathered: Q1. Which ice cream flavor do you think is most popular choice?

Q2. Which ice cream flavor do you think is least popular choice?

Q3. How many people chose vanilla as their favorite ice cream flavor?

Q4. How many people chose peach as their favorite ice cream flavor?

Q5. Which ice cream flavor does you like the most? Now, read the above table and answer the following questions:

## ACT Math Problems

Instructions: This practice test contains 20 questions. You will see your score and the answers to all of the questions when you have completed the test.

You will find problems and formulas for all of the parts of the math test.

The problems include algebra, coordinate geometry, plane geometry, and trigonometric functions.

### ACT Math Problems for Algebra

The algebra questions on the exam cover basic algebraic concepts such as:

• mean (arithmetic average)
• median
• mode
• range
• algebraic fractions
• absolute values
• square roots
• factoring and simplifying polynomials
• algebraic inequalities, expressions, and equations

You will encounter combinations of these concepts in certain math problems on the intermediate algebra part on the test.

So you will often need more than one type of math formula to solve these questions.

For instance, you may see a question that has a fraction that contains another fraction in its numerator or denominator.

Another common type of problem is where an erroneous result is given.

Then you have to use the data provided in order to correct the result.

For example, an average grade may have been calculated for a class, but the score for one student was omitted.

In these problems, you will be given the erroneous average and the omitted score.

Then you will have to calculate the correct average.

### ACT – Geometry

The geometry questions page gives you the math formulas that you need for the test.

On our geometry page, you will learn how to solve coordinate geometry problems, like midpoints, slope, and distance.

Our geometry page also gives you common formulas for plane geometry.

You will see all of the formulas for figures like circles, triangles, squares, rectangles, and cones.

On the geometry page, you will also see formulas for the circumference of circles.

Formulas are also given for the area, angles, perimeter, and volume of various geometric figures.

### ACT – Trigonometry

You will also see the equations that you need in order to calculate trigonometric functions on the math test.

The trigonometry section illustrates the concepts of sine, cosine, and tangent.

It also gives you the math formulas that you need for these trigonometric relationships.
