How is math used in engineering?

Mathematics is a wide discipline and has many forms. In the various engineering fields, different forms of math may be applied to achieve a specific solution. For instance, linear algebra is widely applied in electrical engineering to design electrical circuits. Boolean algebra is the basis of digital logic design, a key component of building computers.\nIn civil and mechanical engineering, geometry is used to design structures and ensure that they perform in a safe and meaningful way. When designing a bridge, civil engineers may use differential equations to calculate the approximate size of ..

How do you figure out the circumference of a circle?

Find the diameterThe diameter is the length across the circle directly through the center. You can measure it in whatever unit is appropriate, such as inches or centimeters. For the sake of an example, say the diameter of your circle is 2.5 inches. Multiply the diameter by piMultiply the number you have times pi. In the example, multiply 2.5 by pi. You can use the rounded off version of pi, 3.14, though most calculators have a button for the longer version of pi. Round off your answerIf you use your calculator's pi button, you end up with an irrational number because pi is irrational, mea..

How many lines of symmetry does a parallelogram have?

A rectangle is a parallelogram with four right angles. This property allows it to have two lines of symmetry.\nA rhombus is a parallelogram with four equal sides. The number of lines of symmetry of a rhombus depends on whether it is a square or not. If it has four right angles, the rhombus is a square and thus has four lines of symmetry. If not, the rhombus only has two lines of symmetry.

What are real life examples of periodic functions?

Trigonometric functions are the most important examples of periodic functions, and these repeat over lengths of 2(pi). These functions are used to describe waves, oscillations and other types of patterns that exhibit periodicity.There are four main properties of periodic functions:The functions cosine and sine have a period of 2(pi).The functions cotangent and tangent have a period of pi.Periodic functions cannot be monotonic, or never decreasing or increasing, on the entire domain.There are specific trigonometric functions for any real number "x" and any real number "k," such as sin(x+2(pi)k)..

What are some pie chart advantages and disadvantages?

Pie charts are built in to many mathematical and statistical software packages, including Microsoft Excel, Minitab, SPSS and R. They are generally simple to create and do not require a lot of explanation when used in a report or a presentation.\nWhile the reader of a pie chart can clearly see which categories dominate, it can be difficult to see categories that occupy only a small percentage of the chart. This problem becomes worse if there are many small categories in the chart. Labeling the categories can also be difficult, leading to either excessively long legends or multiple labels on the..

How are linear equations used?

A linear equation is one with two expressions that are set equal to each other. It can have one or two variables, and the variables can only be raised to the power of 1. In the case of two variables in an equation, the value of one variable always depends on the value of the other variable.\nA common application of linear equations is temperature conversion. In countries that use the Fahrenheit system to measure temperature, such as the United States, linear equations are used to convert temperature from Fahrenheit to Celsius. The equation of a function that converts Fahrenheit to Celsius is a..

How do you make a pie chart?

Collect and organize the dataThe entire sum of data is 100 percent of the result, so whether you have 50 results or 5,000 makes no difference. List each possible response as a fraction of that 100 percent by dividing the given response by the total number of responses. For example, if there are a total of 650 responses and 95 of them are "b," then divide 95 by 650 to get the fraction, or percentage, of response "b." Multiply each fraction by 360 degreesMultiply the fraction for each response. Using the above example, the percentage is 14.6. Multiply 360 by .146, and get the answer 52.56. This ..

What is the end behavior of rational functions?

Three cases exist where the end behaviors of the asymptotes are linear. The first case is where the degree of the denominator is greater than the degree of the numerator. The second case is where the numerator and the denominator have the same degree, and finally, there is the case where the degree of the numerator is greater than the degree of the denominator.

How do you write a scientific conclusion?

The main component of the conclusion should revolve around whether or not the hypothesis can be rejected. If the hypothesis is rejected, the writer should explain what was wrong or which part of the experiment led to the rejected hypothesis. If the study supports the hypothesis, the writer should let the readers know, and outline how the results support it. It is important to be clear and concise when writing the scientific conclusion or any other part of the paper.

What is a "basic fact" in math?

According to the University of Chicago, children should have automatic recall of basic addition and subtraction facts by the time they finish the second grade and automatic recall of basic multiplication and division facts by the end of the fourth grade. Fact extension practice is key when teaching basic math concepts. An example of this is a student learning 3 + 4 = 7, and then learning 30 + 40 = 70 and 300 + 400 = 700.
