What is a period in math terms?

Not all mathematical functions have periods. Some functions, such as f(x) = x, have no recurring values; every value of x gives a different value of f(x). The most well-known periodic functions are the trigonometric functions sine and cosine, both of which have a period of 2pi. The tangent function, tan(x) = sin(x)/cos(x), is also periodic, with a period of pi.

How can you break up numbers from 1 to 1000 in English?

Start with 1 through 10The numbers 1 (one) through 10 (ten) are the basic building blocks of the number system in most languages. By learning 1 through 10, you will have been introduced to every symbol used in the English counting system and the name for when that symbol appears in the "ones" place, which is the right-most digit of a whole number. Learn 1 through 10 before continuing.Learn the irregular numbersIn some languages, the numbers 11 through 19 do not follow the same rules as many of the other counting numbers. In English 11 (eleven) and 12 (twelve) are the most irregular, but the re..

What four-sided shape has only two parallel sides?

A trapezoid is defined by having only one pair of parallel sides. None of the sides are required to be the same length, and the two non-parallel sides can be at any physically possible angles. The perimeter can be calculated by adding together the length of the sides. The formula for the area of a trapezoid is (a+b)*h/2, where "a" and "b" are the length of the parallel sides, and "h" is the distance between those sides.

What is 17 in Roman numerals?

There are several letters in the Roman numeral system used to represent a numeric value. Each individual letter should be translated from the Roman numeral to the Arabic numeral then added together to identify the Arabic numeral equivalent. "XVII", for example, can be translated as "10+5+1+1", which equals 17. The Arabic numeral is then "17". Similarly, "XXVIII" can be translated as "10+10+V+1+1+1", which equals 28. The Arabic numeral is then "28".

What is a tessellation maker?

There are several types of tessellations. Regular tessellations are patterns formed by repeating regular polygons. Semi-regular tessellations are formed from two or more regular polygons with the same pattern at each vertex. Some less common tessellations include demiregular and those with curved shapes. When naming a tessellation, go around a vertex and name the number of sizes each polygon has, starting with the polygon with the least number of sizes.

What are some math terms that start with the letter "J"?

There are many math terms that start with "J," and most of them are named after famous mathematicians. One exception is "jump discontinuity" which occurs when someone drawing the graph of a function on a piece of paper must pick up the pencil to accommodate a sudden change in the function.\nAnother example is "Jacobian," which is introduced in multivariable calculus and refers to a calculation which helps determine the shape of a graph of a function of two variables. A Jordan curve is a simple, closed curve drawn in the plane. A circle is an example of a Jordan curve. Jordan curves divide the ..

What is a commutator subgroup?

The commutator subgroup, also known as a derived subgroup, is a concept found in abstract algebra. The small size of the commutator subgroup makes it an important part of the abelian group, otherwise known as the commutative group. For example, the group G/N is only abelian if N includes the commutator subgroup. The commutator subgroup also measures the abelian nature of a group. A large commutator subgroup means the group is less abelian. Not every element in a commutator subgroup is considered a commutator.

How do you measure a bend radius?

Bend the material to a right anglePlace the cable, wire or other material on a flat surface, and bend it into the shape of a right angle. If the material stops bending or begins offering more resistance, don't try to bend it any further. Hold the material in placeUsing a clamp or other solid object, keep the length of material being measured in place so that it does not lose its bend. It is important that it be placed on a flat, smooth surface with no excess kinks or other deformities that could disrupt the measurement.Measure the angle and distanceSet a carpenter's square or similar..

How is an inverse matrix used in MATLAB?

In Matlab, a matrix can be entered into the computer so the process of finding the inverse matrix is handled automatically.\nFirst, the expressions that are used for such a system of equations in matrix notation are in the form Ax = B, where A and B are matrices, and x is a matrix of variables for which one is seeking a solution. Also, remember that the multiplication of matrices is not commutative, so operations are denoted "left-" and "right-" to indicate the type of multiplication needed.\nFirst, left-multiply the system by the inverse matrix to A (denoted invA) to give:\ninvA * (Ax) = invA..

How do you calculate the perimeter of a circle?

Measure the radiusTake the divider, and stretch it from the center of the circle to any point on the circumference. Transfer the divider to the ruler, and read the measurement. Do not tamper with the stretch of the divider during the transfer to avoid getting an inaccurate measurement. The measurement you get is the radius of the circle. Use a string to measure the radius if the distance from the center of the circle to its circumference is longer than the stretch of the divider. Multiply pi by twoMultiply the value of pi, which is 3.142, by two to get 6.284. You can make the value of pi 22/7 ..
