# Open math problems

It's been a while, but we're excited to re-launch The Math Contest with help from our friends at Casio Education. There are various kinds of students in a mathematics classroom, since there are no tracking in Japanese classroom.

The Open-Ended Problem Solving provides free, responsive, and supportive learning environment because there are many different correct solutions, so that each student has opportunities to get own unique answer s. We will also take a quick look at an application of indefinite integrals.

The Shape of a Graph, Part I — In this section we will discuss what the first derivative of a function can tell us about the graph of a function. We will also give a brief introduction to a precise definition of the limit and how to use it to evaluate limits Tangent Lines and Rates of Change — In this section we will introduce two problems that we will see time and again in this course: More Volume Problems — In the previous two sections we looked at solids that could be found by treating them as a solid of revolution.

Contact Us Welcome Back. Examples in this section tend to center around geometric objects such as squares, boxes, cylinders, etc. We will also give the First Derivative test which will allow us to classify critical points as relative minimums, relative maximums or neither a minimum or a maximum.

Substitution Rule for Definite Integrals — In this section we will revisit the substitution rule as it applies to definite integrals. The integrals in this section will all require some manipulation of the function prior to integrating unlike most of the integrals from the previous section where all we really needed were the basic integration formulas.

For detailed information, please see Instruction for Authors. Derivatives of Hyperbolic Functions — In this section we define the hyperbolic functions, give the relationships between them and some of the basic facts involving hyperbolic functions.

If you have a problem or issue to report, please let us know. Perelman's proof tells us that every three manifold is built from a set of standard pieces, each with one of eight well-understood geometries. We will actually start computing limits in a couple of sections. As we will see starting in the next section many integrals do require some manipulation of the function before we can actually do the integral.

We discuss the rate of change of a function, the velocity of a moving object and the slope of the tangent line to a graph of a function. We also cover implicit differentiation, related rates, higher order derivatives and logarithmic differentiation.

Derivatives of Trig Functions — In this section we will discuss differentiating trig functions. Examples in this section concentrate mostly on polynomials, roots and more generally variables raised to powers.

Definition of the Definite Integral — In this section we will formally define the definite integral, give many of its properties and discuss a couple of interpretations of the definite integral.

One idea is to use a pool, for example. Average Function Value — In this section we will look at using definite integrals to determine the average value of a function on an interval. From an average student to a top 10% student in math!. On this site, Both x and * are used as multiplication signs.

Both / and ÷ are used as division signs. Sample Problems.

Online geometry classes, Tutoring, Tutorial, Tutor. Processes: Problem Solving, Reasoning & Proof, Communications, Connections. My son is in 4th grade and has just started to participate in Math Olympiad contest.

I found this book to be quite handy that he can practice with it, and have discussions with me on his solutions (or non-solutions), then compare with the result from the book.

Free math problem solver answers your algebra homework questions with step-by-step explanations. To supplement the list you found, DIMACS Open problems for undergraduates, there is The Open Problems Project, the latter not specifically oriented to undergraduates.
